If the side length of a face centered unit cell of a metal is 400 pm approximate radius of the metal in pm is `(sqrt(2)=1.414)`

A

14.14

B

35.3

C

176.7

D

141.4

Text Solution

Verified by Experts

The correct Answer is:
D
Edge /side length of a fcc= 400 pm
`because For fcc`
`r= (a)/(2sqrt(2))`
`:. " " r = (400)/(2xx1.414) = 141.4 pm`
