If the crystallises in zinc blende structure with `I^-` ions at lattice points. What fraction of tetrahedral voids is occupied by `Ag^+` ions ?

A

0.25

B

0.5

C

1

D

0.75

Text Solution

Verified by Experts

The correct Answer is:
B
Let no.off i.e., no. of spheres = x
So total no. of tetrahedral voids = 2x
now as no. of `Ag^+` = x which is 50% of 2x
