Explanation:
The atom 2 which would be expected to have a half filled 4s subshell is the potassium atom. Potassium has a electronic configuration 1s2 2s2 2p6 3s2 3p6 4s1 or (Ar) 4s1. The 4S1 subshell is half filled since the s orbital accommodate 2 electron pair to be fully filled.
Group 6 elements usually have extra electrons to make give them an octet. So, they have 6 electrons to start and when they have an octet, they have 8.
We can find the charge by doing simple math 6 - 8 = -2
