NCERT Grade 12 Chemistry Chapter 1, The Solid State deals with different possible arrangements of particles resulting in several types of structures and different arrangements of structural units that lend different properties to solids. In this chapter, students will learn how these properties get modified due to the structural imperfections or by the presence of impurities in minute amounts.
After studying this chapter, students will be able to describe general characteristics of solid state; distinguish between amorphous and crystalline solids; classify crystalline solids on the basis of the nature of binding forces; define crystal lattice and unit cell; explain close packing of particles; describe different types of voids and close packed structures; calculate the packing efficiency of different types of cubic unit cells; correlate the density of a substance with its unit cell properties; describe the imperfections in solids and their effect on properties and correlate the electrical and magnetic properties of solids and their structure.
General Characteristics of Solid State, Amorphous and Crystalline Solids, Classification of Crystalline Solids, Molecular Solids, Ionic Solids, Metallic Solids, Covalent or Network Solids, Crystal Lattices and Unit Cells, Primitive and Centred Unit Cells, Number of Atoms in a Unit Cell, Primitive Cubic Unit Cell, Body-Centred Cubic Unit Cell, Face-Centred Cubic Unit Cell, Close-Packed Structures, Formula of a Compound and Number of Voids Filled, Packing Efficiency, Packing Efficiency in hcp and ccp Structures, Efficiency of Packing in Body-Centred Cubic Structures, Packing Efficiency in Simple Cubic Lattice, Calculations Involving Unit Cell Dimensions, Imperfections in Solids and Types of Point Defects are the topics discussed in this chapter. NCERT Grade 12 Chemistry Chapter 1, The Solid State holds a total weightage of 4 marks in the final examination.
