Copper crystallizes in fcc with a unit cell length of 361 pm. What is the radius of copper atom ?

A

108 pm

B

127 pm

C

157 pm

D

181pm

Text Solution

Verified by Experts

The correct Answer is:
B
For fcc structure
`r = ( a)/( 2sqrt(2)) = ( 361)/( 2sqrt(2)) = ( 361)/( 2 xx 1.414)`
`= 127.6 `pm
