Question

A compound contains two types of atoms - x and y. It crytallises in a cubic lattice with atom x at the corners of the unit cell and atomsy at the body centres. What is the simplest possible formula of this compound?

Answer 1

Answer:

Explanation:

We know there are 8 corners in a cubic lattice.Every particular corner is shared by 1/8th part of each atom.So, number of atoms of x=8*(1/8)=1

There is only 1 body centre in a cubic lattice,where is occupied by a single whole atom.So, number of atoms of y=1*1=1

Therefore formula of the compound is xy.
