Play a game for writing formula.

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.

Do it yourself:

Now, write the formula of sodium phosphate.
