In a solid AB having the NaCl structure, ′A′ atom occupies the corners of the cubic unit

Question

In a solid AB having the NaCl structure, &#8242;A&#8242; atom occupies the corners of the cubic unit cell. If all the face-centred atoms along one axis are removed, then the resultant stoichiometry of the solid is :

Accepted Answer

Na in NaCl has 8 corner and 6 face atoms. If we remove face centred atom of one axis, two face atoms are removed. Thus A is at 8 corner and B is at 4 faces.
∴ A =

= 1 and B =

= 2
Thus formula is AB₂
