WebThe manganese atom exhibits Mn 2+, Mn 3+, and Mn 4+ ion. The manganese atom donates two electrons from the last shell to form the manganese ion(Mn 2+). Mn – 2e – → Mn 2+ Here, the electron configuration of manganese ion(Mn 2+) is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5. This electron configuration shows that the manganese ion has three shells and ... Web1 mei 2016 · In the case of the manganese ions and in other transition metals the forbidden transition is in absorption. The treatment is the same in all cases and starts with allowing the two states to interact via some operator. In the case of photons (absorption / emission) it is an electric dipole operator, i.e. dipole moment operator.
