* Ionic Bonding: Sodium (Na) and oxygen (O) form an ionic bond, meaning they transfer electrons. Sodium has a +1 charge (Na+) and oxygen has a -2 charge (O²⁻).

* Stable Compounds: To achieve a neutral compound, you need two sodium atoms to balance out the charge of one oxygen atom.

Therefore, two sodium atoms will bond with one oxygen atom to form the compound sodium oxide (Na₂O).
