NEET Chemistry The Solid State Questions Solved


In a face centred cubic lattice, atom A occupies the corner positions and atom B occupies the face
centre positions. If one atom of B is missing from one of the face centred points, the formula of the compound is

1.AB2

2.A2B3

3.A2B5

4.A2B

(3)
No. of A atom = 1/8 x 8=1
No. of B atom = 1/2 x 6-1/2=5/2

Hence, formula of compound is AB 5/2 or A2B5.
