If the ratio of coordination no. of A to that iof B is x:y, then the ratio of no. of atoms of A to that no, of atoms of B in the unit cell is

Mention the number of atoms in a b.c.c unit cell.

A substance A_(x)B_(y) crystallises in a face centered cubic lattice. Atoms 'A' occupy each corner of unit cell and atoms of B occupy centre of each face of the cube. Total number of atoms of A and B in the unit cell is __________

The unit cell of a binary compound of A and B has ccp structure with A atoms occupying the corners and B atoms occupying the centres of each face of the unit cell. If during crystallisation of the alloy, in the unit cell two atoms of A are missing, the overall composition per unit cell is :
