An element ‘A’ has face-centred cubic structure with edge length equal to 361 pm. The apparent radius of atom 'A' is :

A

127.6 pm

B

180.5 pm

C

160.5 pm

D

64 pm

Text Solution

Verified by Experts

The correct Answer is:
A
For face-centred unit cell,
`asqrt(2)=4r," "(361xx1.414)/(4)=r," "r=127.6` pm
