A mineral having the formula `AB_(2)` crystallizes in the ccp lattice, with A atoms occupying the lattice points. The coordination number of A and B atoms in its structure are

A

4,8

B

4,4

C

8,8

D

8,4

Text Solution

Verified by Experts

The correct Answer is:
D
Since A atoms occupy the lattice points , B atoms will be in all tetrahedral sites.
`:.` Coordination number of B = 4
Coordination number of A = 8
