Study Notes
Oxidation Numbers and States
- In a pure element, the oxidation number of each atom is zero.
- In neutral molecules, the sum of oxidation states is zero.
Oxidation States of Ions and Atoms
- The oxidation number of an ion of an element is equal to its charge.
- The oxidation state of an atom in a chemical compound represents the number of electrons an atom can gain, lose, or share to form a bond.
Characteristics of Oxidation States
- The oxidation state of an atom in a compound is a formalism, meaning it is a hypothetical or theoretical concept rather than a physically measurable quantity.
- The oxidation state is NOT an actual charge on an atom in a molecule.
- The oxidation state is a useful predictor of charge in many chemical compounds because it helps in predicting the reactivity of atoms and molecules.
