WebMar 18, 2024 · Solution. Since there is only one electron, this is a simple problem. L = 0 and M = 1, so the only possible term symbol is 2 S. With only one electron, ½ S = ½, so ½ ½ J = 0 + ½ = ½. Only one microstate exists for this configuration and it has a term symbol of ½ 2 S ½. Example 8.8. 10: Boron.
