That is, it has 26 electrons. $\begingroup$ In the case of a metal it really doesn't make sense to say "magnesium has no unpaired electrons", there are valence electrons floating around and they are not "paired" in the atomic sense. The key difference between paired and unpaired electrons is that the paired electrons cause diamagnetism of atoms whereas the unpaired electrons cause paramagnetism or ferromagnetism in atoms.. We can see that s orbital has 2 unpaired electrons. We first put 5 of them in different orbitals (Hunds Rule). Following the Pauli exclusion principle and Hund's rule, we place as many electrons as we have (O2: 2 times 6 valence electrons, C2-: 2 times 4 valence electrons plus 1) in the new orbitals. electron configuration is 1s^2, 2s^2, 2p^6, 3s^2, 3p^3 (The exponents add up tp 15).
