Writing Chemical Formulae

Step 1 : Write the symbol of a basic radical (element with the positive valency) to the left hand side and that of the acid radical (element with the negative valency) to the right hand side.

Step 2 : Write the valency number/charge of each of the respective ions at the bottom of its symbol.

Step 3 : Interchange the valency number. Ignore the (+) and (-) sign.

Step 4 : Write the interchanged number.

Step 5 : Write the compound’s formula.

Step 6: Cross the reduced valencies. If 1 appears, ignore it. And if a group of atoms receive a valency number more than 1, enclose it within the brackets.
