... Two possibilities should come to mind: 1s2 2s1 2p2 and 1s2 2s2 3s1. The first leads to several possible states, but with the possibility that the three 2s and 2p electrons could be all spin-aligned and produce a quartet state (there’s the answer to part (e)!), which would be lower in energy than any ...
