The volume of atom present in a face-centred cubic unit cell of a metal (`r` is atomic radius ) is

A

`20//3 pir^(3)`

B

`24//3 pir^(3)`

C

`12//3 pir^(3)`

D

`16//3 pir^(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
Total no. of atoms in fcc unit cell `=4`
Total volume `=4xx(4pir^(3))/3=16/3 pir^(3)`
