Oxidation State Rules and Examples

• Elementary State: Oxidation state is zero.
• Monoatomic Ions: Oxidation state is equal to the charge on the ion.
• Oxygen: Typically -2, exceptions include peroxides and superoxides.
• Hydrogen: +1 with non-metals, -1 with metals.
• Halogens: Usually -1, exceptions when bonded to more electronegative elements.
• Alkali Metals: Always +1.
• Alkaline Earth Metals: Always +2.
• General Rule: Sum of oxidation states in a molecule equals the charge of the molecule.

Coordination Compounds Examples

• Calculation of oxidation states in coordination compounds with specific examples such as [Co(NH3)6]3+, K4[Fe(CN)6], and more.
• Explanation of how to approach these calculations.
