Oxidation States (Oxidation Numbers)

Explains what oxidation states (oxidation numbers) are, and how to calculate them and make use of them.

strictly, zinc, cadmium and mercury aren’t considered transition metals. IUPAC definition of a transition metal states that it must be ‘an element whose atom has an incomplete d sub-shell, or gives rise to cations with an incomplete d sub-shell‘. Zinc, cadmium and mercury all have the electronic configuration d10s2; although they commonly form +2 ions, these involve the loss of the s electrons. However, they can also exist in a +1 oxidation state.

Colorful Oxidation States | Chemistry Demonstrations

This demo has a solution in a flask that changes color from pink to blue to green to yellow to orange as the solution is stirred. The different colors are due to the different oxidation states of Mn.

Oxidation States of Transition Metals - Chemistry LibreTexts

The oxidation state of an element is related to the number of electrons that an atom loses, gains, or appears to use when joining with another atom in compounds. It also determines the ability of an …
