Question

A cubic solid is made of two atoms A and B,A are present at the centre of B at the body predict the formula ratio 1:1 of AB

Answer 1

Answer:

Since P is present at corners of the cube,

So, number of P atoms =  

8

1

​  

×8=1.

Q is present at body centre. So, number of Q atom = 1.

So, the formula of the compound is PQ.

Here, P is surrounded by 8 Q atoms and Q is surrounded by 8 P atoms.

So, the coordination number is 8:8.

Hence, option D is correct.
