Question
In a solid ′AB′ having the NaCl structure ′A′ atom occupy the corners of the cubic unit cell. If all the face centre atoms along one of the axes are removed then the resultant stoichiometry of the solid is :
Options
A.AB2
B.A2B
C.A4B3
D.A3B4
Solution
A ⇒ 8 × 
+ 4 × 
× = 3
B ⇒ 12 ×
+ 1 = 4
A3B4
+ 4 × × = 3B ⇒ 12 ×
+ 1 = 4A3B4
