Question
A compound of A and B crystallizes in a cubic lattice in which A atoms occupy the lattice points at the corners of a cube and two atoms of B occupy the center of each of the cube faces. What is the formula of this compound ?
Options
A.AB3
B.AB4
C.AB2
D.AB6
Solution
for A, 8 × 
= 1
for B, 12 ×
= 6
so AB6
= 1 for B, 12 ×
= 6so AB6
