Problem 1
A solid has a cubic structure in which X atoms are located at the corners of the cube, Y atoms are at the cube centres, and O atoms are at the edge centres. What is the formula of the compound?
Solution
Atoms of X are present at all the eight corners of the cube. Therefore, each atom of X at the corner makes 1/8 contribution towards the unit cell.
Number of atoms of X per unit cell = ![]()
Y atom is presented at the body centre, thus contribution of Y towards unit cell = 1 × 1 = 1
O atom is presented at each of the edge centre (number of edges of cube = 12)
And each O atom present at edge centre will make 1/4 contribution ...
