Solution
Valency of element X = 4
Valency of element Y = 1
Elements : X Y
Valencie: 4 1
Formula for the compound formed between X and Y can be worked out by crossing the valencies of the constituent elements.
Therefore, formula of the compound is XY4.

Example 2: A low-cost model for writing formulae: Take empty blister packs of medicines. Cut them in groups according to the valency of the element, as shown in the figure. Now, you can make formulae by fixing one type of ion into other.
For example:
The formula for sodium sulphate:
2 sodium ions can be fixed on one sulphate ion.
Hence, the formula will be Na2SO4.
