Class 12 Chemistry Chapter 1: Solid State – Important Topics

Some of the important topics in Class 12 Chemistry Chapter 1: Solid State is given below

Types of Solids – Crystalline and Amorphous Solids

Properties of Crystalline Solids:

They have fixed geometrical shapes.
Crystalline solids have their constituent particles arranged in long-range order.
They have a fixed melting point.
They have fixed heat of fusion.
They are anisotropic.
They are considered as true solids.

Properties of Amorphous Solids:

They have an irregular shape.
Amorphous solids have their constituent particles arranged in short-range order.
When heated, they soften and do not have a sharp melting point.
They do not have a sharp melting point.
They are isotropic.
They are considered as pseudo solids or super cooled liquids.

Types of Bonding – Ionic Bond, Covalent Bond

Ionic Bond: Ionic bond is formed by the exchange of electrons between two reacting molecules. It usually occurs between metals and non metals (eg: Sodium and Chlorine) where there is an interchange of oppositely charged particles.

Covalent Bond: Covalent Bond is the sharing of electrons between two molecules to form a new product. This types of bonding is not as strong as Ionic bonds.

Some of the factors which determine the type of Bonding are called as Bond parameters. They include:

Bond Length
Bond Angle
Bond Enthalpy
Bond Order
Resonance Structures

Lattice Enthalpy: It is the amount of energy required to separate one mole of crystalline ionic compounds from its constituent gaseous ions.
