Unit Cell and Packing Efficiency (The Solid State - 9) || Chemistry for Class 12 in Hindi

In this Chemistry video in Hindi for Class 12 we explained what a unit cell in crystal lattice is and what is packing efficiency. We also evaluated the number of atoms inside a unit cell for different types, viz., Simple Cubic Unit Cell, Face-Centred Cubic Unit Cell and Body-Centred Cubic Unit Cell. This is a topic from the chapter 'The Solid States' for Class 12th Chemistry. The unit cell is defined as the smallest repeated unit of full crystal structure / lattice. 👇👇👇👇👇👇👇👇👇 𝑷𝒍𝒂𝒚𝒍𝒊𝒔𝒕 👇👇👇👇👇👇👇👇👇 🔴 THE SOLID STATE - FULL CHAPTER 🔴 Class 12 - Chemistry    • Chemistry 12th : The Solid State   👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆👆 Previous videos :- 🔴 The Solid State    • The Solid State (Introduction) || Chemistr...   🔴 Types of Crystalline Solids    • Types of Crystalline Solids (The Solid Sta...   🔴 NON POLAR molecular solids and LONDON dispersion forces    • NON POLAR molecular solids and LONDON disp...   🔴 Polar Molecular Solids and Hydrogen Bonded Molecular Solids    • Видео   🔴 Ionic Solids    • Ionic Solids (The Solid State - 5) || Chem...   🔴 Metallic Solids    • Metallic Solids (The Solid State - 6) || C...   🔴 Covalent or Network Solids    • Covalent or Network Solids (The Solid Stat...   ***********************************************************************************************
