Given information
Given:-aluminum and oxygen
Step-by-step explanation
Step 1.
The molecular formula is prepared by balancing the valencies of the constituents. Valency of anion and cation are neutralized to obtain the molecular compound.
Here, for the formation of a molecular compound, the valency of both elements is counted.
Here, symbol and charge of aluminium =
and, symbol and charge of oxygen =
Adjusting the subscript on each cation and anion, we get .
