A given metal crystalline out with a cubic structure having edge length of `361` pm .if there are four metal atoms in one unit cell, what is the radius of metal atom?

A

127pm

B

80 pm

C

108 pm

D

40 pm

Text Solution

Verified by Experts

The correct Answer is:
A
For fcc ` r = (sqrt2a)/(4) = (1.41 xx 361)/(4) = 127 `pm
