A substance

{A_X}{B_Y}

crystallises in a face centred cubic (fcc) lattice in which atoms

'A'

occupy each corner of the cube and atoms

'B'

occupy the centres of each face of the cube. Identify the correct composition of the substance

{A_X}{B_Y}

View answer and explanation

Correct option: A

A{B_3}

Option A (

A{B_3}

) is correct because the number of atoms of A and B in the unit cell are calculated based on their positions in the FCC lattice, giving a ratio of 1:3.
