AB crystallizes in a body centred cubic ...

`AB` crystallizes in a body centred cubic lattice with edge length `a` equal to `387p m` .The distance between two oppositely charged ions in the lattice is :

A

335 pm

B

250 pm

C

200 pm

D

300 pm

Text Solution

Verified by Experts

The correct Answer is:
A
For bcc lattice, body diagonal = `asqrt3` .
The distance between the two oppositely charged ions
` = a/2 sqrt3 = (387 xx 1.732)/(2) = ` 335 pm
