A metal crystallises in a face centred cubic structure. If the edge length of its unit cell is 'a' the closest approach between two atoms in metallic crystal will be

A

2a

B

`2sqrt(2)a`

C

`sqrt(2)a`

D

`a/(sqrt2)`

Text Solution

Verified by Experts

The correct Answer is:
D
If fcc, the closest approch distance between two atoms,
`d = a/(sqrt2)`
