Learn how to write out the electron configuration of sodium and magnesium using the diagonal rule also called the Madelung's rule. The s orbital can hold 2 electrons, the p can hold 6 , the d orbital can hold 10 and the f can hold 14. Sodium has 11 electrons so the electron configuration is 1s2 2s2 2p6 3s1 Magnesium has 12 electrons so the orbitals fill up as follows, 1s2 2s2 2p6 3s2 You may also enjoy Valence Electrons https://www.youtube.com/watch?v=YbpsDiTBejI
