2. Write the ground-state electron configuration for the following atoms and ions. Indicate how many
unpaired electrons each has (you can use the short-hand (abbreviated) notation if preferred and draw only
the outermost/valence orbitals to show the electron filling diagram).
a) 'Mg' as an example: Mg has 12 electrons
Ground-state electron configuration for Mg is 1s² 2s² 2p 3s² or [Ne] 3s² (in short-hand or abbreviated)
Orbital diagram has all the orbitals filled. So, there are no unpaired electrons in Mg.
