Question

Distinguish between the solids in the following pairs.

a. crystalline solid and amorphous solid

b. ionic solid and molecular solid

c. molecular solid and network solid

d. metallic solid and network solid

Short answer

1. Crystalline Solid- Regular repeating structure, Amorphous Solid – Irregular structure.
2. Ionic Solid- Form ionic bond, Molecular Solid-Form weaker covalent bond.
3. Molecular Solid- Form weaker covalent bond, Network Solid- Form covalent bond in a continuous network.
4. Metallic Solid- Conduct electricity, Network Solid- Acts as insulators or semiconductors.

Step-by-step solution

Determine the difference between crystalline solid and amorphous solid

The solid with a regular repeating structure is the crystalline solid, while the solid with an irregular arrangement of atoms is known as the amorphous solid.

Determine the difference between Ionic solid and Molecular solid

The solid formed by combining ions is an ionic bond, while the solid formed by combining weaker covalent is known as a molecular solid.

Determine the difference between molecular solid and network solid

From step 2, we know that the solid formed by combining weaker covalent is known as a molecular solid. In contrast, the solid formed by combining covalent bonds in the continuous network is known as a network solid.

Determine the difference between Metallic solid and network solid

The solids that behave as insulators or semiconductors are known as network solids, whereas the solid with delocalized electrons and can conduct electricity is known as metallic solid.
