A cubic solid is made of two elements P and Q. Atoms Q are at the corners of the cube and P at the body centre. What is the formula of the compound?

Text Solution

Verified by Experts

As atoms P are present at the body centre, therefore, number of atoms of P in the unit cell = 1.
As atoms Q are present at the 8 corners of the cube, therefore, number of atoms of Q in the unit cell = `1/8 xx 8` = 1
Ratio of atoms P:Q=1:1
Hence, the formula of the compound is PQ.
