1.	A unit cell consists of a cube in which the atoms A are occupying the corners while the atoms B are present at the centre of each face. If the atoms A are missing from 2 corners, what is the simplest formuls of the compound ?
Answer» Correct Answer - `AB_(4)` Contribution by atoms A present on six corners of the unit cell = 6/8 = 3/4 Contribution made by atoms B on the centre of all the six faces = 3 The atoms of A and B are in the ratio 3/4 : 3 = 1 : 4 Formula of the compound = `AB_(4)`.
