A cubic solid is made up iof two elements X and Y . Atoms Y are present at the corners of the cube and atoms X at the body centre. What is the formula of the compound ? What are the coordination number of X and Y ?

A

`PQ_2`, 6:6

B

PQ,6:6

C

`P_2Q`,6:6

D

PQ,8:8

Text Solution

Verified by Experts

The correct Answer is:
D
No. of atoms of P =`8xx1/8`=1
No. of atoms of Q = 1 x 1 =1
The formula of compound is PQ
Coordination no. of P and Q = 8:8
