In a face centred cubic lattice, atoms of A form the corner points and atoms of B form the face centred points. If two atoms of A are missing from the corner points, the formula of the ionic compound is :
Options
- AAB ₃
- BAB ₄
- CA ₂ ~B ₅
- DAB ₂
Correct answer
B. AB ₄
Step-by-step solution
A form corner points and two atoms of A are missing from corner aligned & Atoms at corner ( A )=6 1 8 = 3 4 & Atoms at face centre ( B )=6 1 2 =3 & A _ 3 / 4 ~B ₃ i.e., AB ₄ aligned
