- shells. The rule states that for a given electron configuration, the lowest energy term is the one with the greatest value of spin multiplicity. This implies...6 KB (787 words) - 21:15, 18 February 2024
- indicates that the multiplicity 2S+1 = 3, so that the total spin S = 1. This spin is due to two unpaired electrons, as a result of Hund's rule which favors...7 KB (814 words) - 22:54, 5 September 2023
