Document Summary
When transition metal cations are formed, their 4s electrons are lost first. Many transition metal ions have unfilled d orbitals. For the first several transition metals in the fourth period, the maximum oxidation state of the metal corresponds to the number of valence electrons. The stability of the lower oxidation states increases across the fourth period transition metals. The stability of electron configurations in which there are unfilled d orbitals leads to multiple stable oxidation states, characteristic colours, and unpaired electrons. The ion dipole interactions between water and transition metal ions are very strong. Transition metal ions can act as acids in water and produce aqua complexes. Iron can bond up to six water ligands. Ferric is more acidic than ferrous because of its higher charge. Hydroxo and oxo complexes tend to be less soluble or insoluble. Life evolved in the absence of oxygen gas. When the earth became cool enough to form oceans, h+ was the strongest oxidant available.
