Answer and Explanation:
Oxygen is written as O2 when there are two oxygen atoms in the molecule. Pure oxygen doesn't generally exist as individual atoms, two oxygen atoms bond together to form an oxygen molecule.
Na is metallic sodium. It is not diatomic.
The gases become diatomic because it gets them their preferred 8 valence electron shell, you can see why noble gases have no need to be diatomic.
Na is not diatomic because it's so reactive, sodium is only found in nature as a compound--never as a free element.
The only diatomic molecules are H2, N2, O2, F2, Cl2, Br2, and I2.
