A cubic solid is made up of two atoms A and B. Atoms A are present at the corners and B at the centre of the body.
What is the formula of the unit cell ?

Text Solution

Verified by Experts

Contribution by the atoms A present at eight corners = 1
Contribution by the atom B present in the centre of the body = 1
Thus, the ratio of atoms of A : B = 1 : 1
Formula of unit cell = AB
