The Iron Triad is a historical name for the group of elements Fe, Co, and Ni. It was used to refer to these elements in the same period that share similar chemical and physical characteristics. All three elements in the Iron Triad can form +2 and +3 ions. For each element: a) Write the neutral, +2 oxidation state, and +3 oxidation state electron configuration using the condensed noble gas notation. Indicate which ions in the group are isoelectronic. b) Indicate the number of unpaired electrons in the +2 and +3 oxidation state and whether each ion is diamagnetic or paramagnetic.
