solid state 12th chemistry|| chapter 1 || part3 sachin sir #solidstatechemistry @a2zpractical991

Hello everyone, how are you all? I think you must be having a great time in your life and surely watching the eight-digit practicals. So, today I've brought part 3 videos for your chemistry 12, Chapter 1, Solid State So, I've brought you to part 3 of the solid state. I am doing this chapter very well for you. I have already finished the halogen derivatives of alkanes. Toh please make sure he definitelyPropertyChanged. Related to physics, chemistry, and biology for you on this channel These are practicals. How to score 30 out of 30 marks? All these things have been provided here. And all the practicals have already been completed. Please go ahead and be careful. Don't waste even a moment. 场馆，我将要进行第一章，固体状态的内容。 I'm about to start. So, kids, in parts 1 and 2, we have already I've seen so many things. Now we'll move forward on our own. Because life is about moving forward. Come on, now we're here Step by step, we will move forward. So, today's children, today we will study Today, we'll basically study crystal structures. What exactly are crystal structures? You would know that our little ones Atoms and molecules exist, and they combine with each other. What are you doing with each other? Getting together. Someone or other always does. Structures form. This is called crystal structures. Let's take a look at this from the perspective of chemistry. What do we call this? The arrangement, the ordered Three-dimensional arrangement of the particles. Ordered my own and another 3-dimensional arrangement It's about particles. That's what forms structures. Look, the one I have How is the arrangement? It's 3D. Because you're also facing me from the front. You can see it from the front and also from behind. So, one ball Lelu, if I take his example, I can see him everywhere. That's why that structure is called three-dimensional. Arrangement. What do you say to him? Three-dimensional arrangement. To, the ordered, it should be ordered, and it should be a 3-dimensional arrangement of some particles. Then that What does it show us? It shows crystal structures. So, let's see. Crystal structures basically ours These are happening. Do you see? Look, if Make a structure like this. This is called 2D type. What do you say about this? 2D type. And if I make it like this. To, look here, this is a 3-dimensional arrangement. How is this? It's 3-dimensional. I have an arrangement in mind. Look, one below the other. One below one. One below one. One below one. We call such a crystal, such a system, a crystal. structures. What do you الساعة a crystal system like this? Crystal structures. I think you'll gradually understand crystal structures. It will be. There are two types of crystal structures. For the children. One of us will read the lattice, and the other child, we will read together. Basis. So, let's see what a lattice is? What is this lattice? So, lattice There is a point like this where atoms, ions, or molecules are attached. For example, if If you want to build a structure, what must be done first at the bottom of the building? By hating the constituent particles by hating constituent particles of each of the lattices. Of each of the lattices. And that is called the basis. Base metal Crystal Creek Viswa Padikal, you are the molecular enjoyer, the sole talaj paktar, the deceased Pooja parts, mix up the lattice point. Someone always attaches to some constituent particle or another. Children call these constituent particles "Bachchu bases." What does it say? Based on these constituent particles, say. This means that which has cubic structures of national They move to an unstable particle at some position. The particles of the CL of arises are present. Those particles of Na and CL These are the positions of GPS. That same Ani and that same Lakshmi they were Its name was Baisi Basiss. What do you make by combining everything? Made from crystal Let me see if my elder understands something. If you didn't understand the abashī So I'll do something for you here, listen carefully, watch closely, just you stay here with the children Alright, I'll sweeten it first. Now, look, I need to build a house, so I I'll have to make a blueprint first. The kitchen should be here, the living room should be here, the store should be here. Alright, I've made the blueprint. I'll start making the frame, it's okay, place it on top of this blueprint I'll start, is it done, what about ours, basis, is it done, what about ours, basis, and Jesi I'll keep it, the whole house, the building, the block, everything ready, so my house What will happen to the house, children, it will be ready, and just as our house will be ready once it's built, that's exactly it. You would have understood by now that if I create a blueprint of the building, and then place a block on top of that blueprint, that block becomes our basis. Once both come together and fit perfectly, that's when we're ready. You have been appawar, and if the vagra is kept, a bus has been made for a beat of the print block for our ladwa. A unit cell is the smallest repeating unit in a crystal structure that retains the overall symmetry of the crystal. Srap is now a solid at the edge. So, the smallest structure we refer to is called the unit cell. What do they call that unit cell? Batala has become one of our units. Now, a large number of small, scattered units have been combined together within its arms. You will know about the crystalline stock exchange for Karharaud. Crystal will now know Asalied. That's what they keep saying, but from the video And sold, a thing, time grains give me Exactly perfect, as written on the board: if asked, write the smallest repeating structural unit of a crystal, which is the unit cell. Observe: if we are forming a crystalline solid, then that... The roots of Nejzardar have spread, spreading widely. Many small, scattered units exist. They are his own, what取决于 a few YouTube cells, which are not from the Chauraha, let's go, kids, the unit cells we have Whatever we create as a unit cell will necessarily have some points and some axes. So, look, this is how our unit cell is formed; this is our unit cell right here. So, one, one, we call the axis that comes out the y-axis, okay? And what should we call this one, x, y — it's done. Now, what should we call this one, z? And if it keeps forming some kind of angles, we can call this alpha. Okay, we can roll this. Gammy, and what can we call this, beta? So, in the unit cell we create, there are three axes present, which are x, y, and z. And the three angles of ours are alpha, beta, and gamma. I think this is the best explanation, and you must have understood this very well. So, kids, please do one thing: if you're enjoying these videos, kindly subscribe to this channel and definitely like this video. They are primitive and simple units. What are primitive and simple unit cells? And after 10 cuts, the remaining part of the thread is the previous one. One, this will be a challenge later, and the cracks will be taken by eight, the chosen ones will be the ones to overcome the challenge. What do they call it, the Bahu Sented Indri Cell? If you didn't understand, just look carefully—now you'll see. The barbed wire is fully in place. You see, this red one is your presentation, and the one in the middle is also your presentation. The presentation is in the middle; look at the respect, where is the respect? Look at the level; one, two, three, four, five, seven, eight — all are present. The moonlight, scattered and dim, quietly illuminates the path, casting shadows that seem to whisper ancient tales through the silent night. Twelve, I got it, Opone, I'm stuck, start oath, bag went, come see here Bhachp. So, two particles were also present in this park, called Bhilkool, near Pares. You all take one particle and one tea or eight yesterday opened A single, identical crystal fragment The raw particles of Rapdo Particles, there in Kasara, Your face is there, and the rest are fighting—additional to your companion's wish. No no no no no no no no no no no no no, the type of Vachchiyora is very rare, it is a Gendjara. Is it also seen as extremely unattractive, just like how it's perceived? Have the people understood what a simple cubic unit cell is? So, Kanar, you're here now What happens at Body Center? They are called Kanwar, and even in the middle, there is a Kanwar. And last, your face center Your faces will be there You will be told one by one, particle by particle. Look at the face; this will be the upper face. This will be the front face, this will be the side face, this will be the bottom face They will stay there, one by one particle. And eight will stay at the corner. And that's all we have, kids. That's it, Kriti Unisal. So, what exactly happened to Kriti in Unisys? Where will the particles be located on the opposite faces? Take it from here, take it from here, whether from ahead or behind, take it. And at the corner, we'll turn again At the corner, your eat-at-home will be saying, "Children" You will understand this, you will be present Then I'll keep moving forward, okay? If you have any doubts, please definitely comment in the comments section. They will be present on the children, they will be present on the children We will present Your cubic, in the cubic, three types of braided lattices are placed Look here, all the atoms are at the corners, one in the center, and one on the six faces How many Bravais lattices are there in cubic, total 14 Bravais lattices exist, but if specifically asked for cubic, would you write only 3, or would you write 14? No, sometimes they ask, so how many in rhombohedral? So how much will you write, don't just write 4, 14, if only asked, tell me the total number of Bravais lattices present in our entire system, across our entire universe, okay? So there are 14 Bravais lattices in our system, present, tell me what these Bravais lattices are, that's separate. When building structures, the total number of different crystal structures observed so far is 14. These are the various ways atoms arrange themselves, right? As you can see all these, right? Okay, now that we've covered that, let's move on to crystal systems. Yes, I forgot to tell you one thing, dear. What did I forget to tell you? There's a mnemonic trick to remember this. Qubit Tetragonal, Arthorhombic, Rhombohedral, Monoclinic, Triclinic, and Hexagonal If you're not getting it, I'm going to tell you a trick. First, the Simple Cubic Unit Cells. Look at this structure; we call it the Simple Cubic Unit Cell. What is in it? 8 This is after the event. The second one is the Body-Centered Unit Cells. And after Ipane Jārād, my videos come for the purpose of parakushan. That sacred inner light descends from above, a sword below. We will see about that. Dharni's Patbakan Setar Unit Cell They don't understand me at all. Here is a grain of sand so tiny Toate's fesh. If you understand everything, please definitely leave a comment in the video's comment box. That you, sir, have studied very well, okay. Let's move on. Now we will see the number of particles in the cubic unit cell. So, what exactly is the number of particles? Look here. Why, why, because in what we read, it doesn't come out to find the number of particles, it's simple How many particles are there in a cubic nit compared to a body-centered one, and how many particles are there in a face-centered one? You will definitely come, let's go. We'll read the first child, we'll read the first one, primitive and simple. Is it clear? Tell me, in a simple cubic unit cell, how many particles are there? Say it out loud—just one, okay. Let's move on. Now let's look at the body-centered unit cell. Now observe—this is your body-centered unit cell. What is this? This is your body-centered unit cell. Now here... You're looking, you're seeing. 8 are present at the corner. 8 are present at the corner. If 8 is present at the corner, then the eighth part is the part of eight. It has a rebel, one cube here, another cube there, but not a square together over there. So, you'll divorce it? Alright, so what will one plus one be? So Big Center Cubik Nirsil in How many numbers or particles are there, kids? You are the one who is number or particle Keep in mind that he cannot speak. It will not be possible to say the time in Azeri. That's it, let's go. We'll see ahead. face-centered cubic unit cell What I had realized in the face-centered cubic unit cell We see our particles on the faces. First, look at the one who is eating, then empty the cup. One by one No one will ask, sir, where this one-by-eight is from. Because it is a two-part article One, two, three, four, the yellow ones Only one eighth of this cube remains. It's just the rest of the part; what has been done with忺 other people When the cubes are made here by Skhre It's done now in face-centered. What are our six faces present? How many faces are present in six? There is a face, a front face, a belly face, a forward face, a bottom face, a back face. Six faces, one particle is present. And those particles are not his whole self. Half is his and half is someone else's. Look, if I create a structure here among the goods, I make a cube It will come free if you do this. So, what will be the total of free plus one? FCC, that is face-centered in a face-centred cubic unit cell How many particles will come, son? Four will come today. How many will come, Foor? Okay. I understood, I had six into a one-by-two cube because look This is a face; what about yours? A face, a particle on the face, accustomed to it Together shared, the other cube's It's shared together, okay, everyone understands. I came across this, primitive and simple In a cubic unit cell, number of particles How many will they be, one, in BCC Now we will move forward, more We will move forward without holding tension, forward It's our relationship between molar mass, density of the substance and the edge length of the unit cell and reduced in the following step So now we have all these things I need to find a relation, and the children Let me inform you that this time, in 2023 Yes, This appeared in your exam in 2023. Vaccines, and How many two-mark questions appeared in the exam, marks? This is also very important, according to this. A formula is formed, what is formed, one Formula, so let's see what we're going to do with this. We will solve it, then we will have this relation Applicators, age length, density, molar mass Whoever is putting it on, we are putting it on whom? Those of us who are putting them on, the children, we all are the ones putting them on, On top of a cube, what is placed on top of it, On top of the cube, now pay attention, In the cube, these lines that you see, these lines that you have What do you say, do you? Tube, first we write, That one Spindle Cubic Vadum Aat Sodhaf Aogun Badowl Will the wedding ceremony be held at your home? Pyaagtaadi Kishyals Total Volume Here With regard to the matter Is volume with us forever? dm or cmpable because of us of Diplomastika What will happen if the yacuber's kalovel is removed? It will shake, something will stick, a flavor will remain—this is the essence of the experience. What is Squid Game to you, kid? Okay? Now, are there any peka particles here? Each one will have their own month. But isn't there a particle? There are n particles. So, how will you calculate the mass? m x n, correct? If I do m x m, what will I get? Nabhar Masdeosu here, I am a man of the Rast, and I will go to the place of the sacred fire, for the sake of the year's journey, you have come here. I have already told you earlier. What will you read, Hak? You won't do it, sir, you won't do it Molar mass is equal to the mass of one particle. mass of one particle into Avogadro's number How can I represent Avogadro's number? With nₐ, with a dot above To recall the formula for molar mass, write the mass of one particle multiplied by n particles, where n represents the number of particles. nothing but what, Avogadro's number you can write directly, then molar mass is equal to m is equal to What will happen to you? Big guy, common man The big guy will get angry over the mango. Small m Into What will your EBCID number be? Any Okay? Come on Now I am the small-sized mango Just leave it be. That's my job. So, the elder ones will come here. What will happen? Ane Your account number three has just been completed. I'll take it. What should I do now? Look, what am I going to do now? Put Two in Three
