If the aluminium salt of an anion X is Al2X3, what is the valency of X ? What will be the formula of the magnesium salt of X?

To find the valency of X in the aluminium salt Al2X3

Element                     Al                 X
Valency                      3                   2

Therefore, the valency of X is two.

The find the formula for the magnesium salt of X:
Element                      Mg                X
Valency                       2                    2
On crossing the valencies we get the formula of the magnesium salt of X i.e. MgX.
