Question

What name is given to the solid having a regular, repeating molecular pattern?

Answer 1

Arrangement of molecules in solids:

1. The molecules of a solid are closely packed together. This shows that the intermolecular force is the strongest in solids.
2. Since the intermolecular force is strong, the molecules in solids cannot move. Thus it has a fixed shape and volume.
3. Solids, therefore, have a regular, repeating molecular pattern that is crystalline.
4. Hence, the molecules are arranged in a regular repeating pattern called a crystal lattice.
