Question

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

• A. simple cube
• B. body centred cube
• C. face centred cube
• D. None of these

Answer 1

Answer: (B)

body centred cube

Answer 2

The intermetallic compound Li - Ag crystallizes in a cubic lattice in which both lithium and silver have a coordination number of eight. The crystal class is body-centred cubic.
The coordination numbers of simple cubic, body-centred cubic, hexagonalclose packing and face-centred cubic are $6,8,12$ and $12$ respectively.
