An ionic compound has a unit cell consisting of A ions at the corners

1.	An ionic compound has a unit cell consisting of A ions at the corners of a cube and B ions on the centres of the faces of the cube. The empirical formula for this compound would be
Answer» AB `A_(2)B` `AB_(3)` `A_(3)B` SOLUTION :Number of A IONS PER UNIT cell `=(1)/(8)xx8=1` Number of B ions per unit cell `=(1)/(2)xx6=3` Empirical formula `= AB_(3)`.
