A compound `AB_(x)` is formed such that `A` atoms are at corners and `B` atoms at face centre. Find the value of `x`.
Text Solution
Verified by Experts
The correct Answer is:
3
A atoms are at corners. `:. `No. of `A` atoms per unit cell `=8xx(1)/(8)=1` `B` atoms are face centre. `:. ` No. of `B` atoms per unit cell `=6xx(1)/(2)=3` `:. AB_(x)=Ab_(3) :. X=3`
