The edge length of a face centred unit cubic cell is 508 pm. If the radius of cation is 110 pm, the radius of anion will be

A

144 pm

B

288 pm

C

618 pm

D

398 pm

Text Solution

Verified by Experts

The correct Answer is:
A
For fcc structure,
`(r^(+)+r^(-))=(a)/(2)=(508)/(2)=254` pm
`r^(+)=110 rArr r^(-)=254-110=144` pm
Hence, (A) is the correct answer.
