Answer:
The Chemical formula of sodium is Na.
The Chemical formula of oxide is O.
Explanation:
Therefore we know that the term 'valency' is called as the combining capacity of an atom of an element.
So by taking the valency of Sodium and Oxide, we get
Sodium with valency '1' and Oxide with valency '2'.
Na O
1 2
When you cross over you get 'Na2O' as the formula for sodium oxide.
