. In a face centered cubic lattice atom


(A) occupies the corner positions and atom

(B) occupied the face centre positions. If one atom of

(B) is missing from one of the face centered points, the formula of the compound is

A: A2B5   

B:A2B     

C:AB     

D:A2B       

 

Best Answer

Explanation:-

  •  Total number of (A) atoms if it occupy all corner position=1/8× 8=1
  •  Total number of (B) atoms if it is missing from one of the face centered position=5×1/2=5/2
  • Formula of compound is  

 face centered
