All inner electrons are paired, we will look at their valence electrons.
For the orbital diagram, we simply need to draw each orbital and fill them up with the correct number of electrons. Take note that we need to follow Hund’s rule when filling up the orbital diagram. Hund’s rule states that degenerate orbitals (same energy) are first half-filled before being totally-filled.
1.) Group 4A
Group 4A → 4 valence e-
valence electrons: ns2np2
2 unpaired electrons
2.) Group 6A
Group 6A → 6 valence e-
valence electrons: ns2np4
2 unpaired electrons
3.) The halogens
How many unpaired electrons are present in the ground state of an atom from each of the following groups?
1.) Group 4A
2.) Group 6A
3.) The halogens
4.) The alkali metals
