The first electron affinity is the energy released when 1 mole of gaseous atoms each acquire an electron to form 1 mole of gaseous -1 ions. The highest energy level, = 4, so the two electrons lost will come from the 4s orbital. Example 1: Chromium Cr's electron configuration, following the model would be: 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 4 , but instead it is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 1 3d 5 , because there is extra stability gained from the half-filled d orbital. Hund's rule states that the most stable arrangement of electrons (for a ground state electron configuration) has the maximum number of unpaired electrons, all with the same spin. If we look at the electronic configuration of Mn2+ , it is 1s2 2s2 2p6 3s2 3p6 4s0 3d5 . L'atome de manganèse isolé a pour représentation de Lewis : Mn ; dans … Therefore, Mn2+ is.
