In a solid AB having the NaCl structure,...

In a solid `AB` having the `NaCl` structure, A atom occupies the corners of the cubic unit cell. If all the face-centred atoms along one of the axes are removed, then the resultant stoichiometry of the solid is

A

`A_(3)B_(4)`

B

`AB_(2)`

C

AB

D

`A_(4)B_(3)`

Text Solution

Verified by Experts

Ideally A = 4, B = 4, after removing all the face center atoms along a line A = 3 B = 4
`therefore` formula is `A_(3)B_(4)`
