The atomic radius of strontium `(Sr)` is `215 p m` and it crystallizes with a cubic. Closest packing . Edge length of the cube is `:`

A

430 pm

B

608.2 pm

C

496.53 pm

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
`d = (zM)/(N_A a^3)`
`Z = 4 , a = sqrt 2sqrt2 r = 2sqrt2 xx 215 = 608 .2 ` pm
