Lecture 13 => Review of Lecture 12 Periodic Trends: n electronic configuration: General rule for forming main Ion electronic configuration: General rule for forming main group cations (groups 1 2, 13 18): “last in, first out”. Not so for transition element or rare earth cations. First out are valence shell ns electrons, then d electrons. The only transition metals with cation charges (in solution) of +1 are from group 11, e.g. Cu +1 = [Ar]3d 10 . Up to group 7, highest oxidation state is = group number, but id ti tt l ( M 2 t M + lower oxidation states also common (e.g. Mn +2 (aq) to Mn 7+ in MnO 4 . Most transition metals have multiple oxidation states.
