A compound formed by two elements M and ...

A compound formed by two elements `M` and `N`. Element `N` forms ccp and atoms of `M` occupy `1//3rd` of tetrahedral voids. What is the formula of th compound?

A

`M_2N_3`

B

`MN`

C

`MN_3`

D

`M_2N`

Text Solution

Verified by Experts

The correct Answer is:
A
Suppose no. of atoms of M =a
No. of tetrahedral voids = 2a
No. of atoms of N =`1/3xx2a="2a"/3`
Ratio of atoms of M and N =`(2a)/3`: a=2:3
Hence, the formula of the compound =`M_2N_3`
