Show the formation of sodium oxide [Na 2 O] by the transfer of electrons between combining atoms.

The electronic configuration of Na is 2, 8, 1. It is an electropositive element, which can attain the electronic configuration of the nearest noble gas by donating one electron from its valence shell, so as to form sodium ion. The electronic configuration of O is 2, 6 which needs two electron to attain the electronic configuration of the nearest noble gas. Therefore two sodium atom will combine with one oxygen atom to form sodium oxide.
