Question

The intermetallic compound LiAg crystallises in cubic lattice in which both lithium and silver have coordination number of eight. The crystal class is ______.

Options

• simple cubic

• body-centred cubic

• face-centred cubic

• none of these

Answer 1

The intermetallic compound LiAg crystallises in cubic lattice in which both lithium and silver have coordination number of eight. The crystal class is body-centred cubic.

Explanation:

The intermetallic compound LiAg crystallises in a cubic lattice where both lithium (Li) and silver (Ag) have a coordination number of 8. This is characteristic of the body-centred cubic (BCC) structure, in which:

1. Each atom is surrounded by 8 nearest neighbours.
2. Atoms occupy the corners and the body centre of the cube.
