Sodium metal crystallises in body centre...

Sodium metal crystallises in body centred cubic lattic with cell edge 427 pm .Thus radius of sodium atom is

A

429 pm

B

`214.5` pm

C

186 pm

D

185 pm

Text Solution

Verified by Experts

The correct Answer is:
D
in bcc stracture radius `(r )` is related to edge length by
`r = sqrt(3)/(4) a = sqrt(3)/(4) xx 427` pm `= 185 = 185.67 = 185` pm
