Sodium metal crystallises in body centre...

Sodium metal crystallises in body centred cubic lattic with cell edge `4.29 Å` .What is the radius of sodium atom ?

A

5.27Å

B

0.93Å

C

1.86Å

D

3.22Å

Text Solution

Verified by Experts

The correct Answer is:
C
In bcc the atoms touch along body diagonal
` therefore 2r + 2r = sqrt3a`
` therefore r = (sqrt3a)/(4) = (sqrt3 xx 4.29)/(4) = 1.857 Å`
