The correct formula for sodium oxide is Na2O.

Here's why:

1. Sodium (Na) is a metal from group 1 of the periodic table. This means it forms +1 ions.

2. Oxygen (O) is a non-metal from group 16 of the periodic table. This means it forms -2 ions.

3. When these two ions combine to form a neutral compound, we need two sodium ions (2*+1 = +2) to balance the charge of one oxide ion (-2).

So, the correct formula is Na2O.
