Oxidation States Demystified: Quick Redox Guide
Oxidation states track electron accounting
Oxidation states assign each atom a number showing net electrons lost or gained (or shared) versus elemental form; sum to zero for neutrals and to ion charge.
Neutrality and charge fix unknowns instantly
Once you know common oxidation states (e.g., H=+1, O≈−2, Group 1=+1), the remaining atom’s oxidation state is forced by the rule that totals equal overall charge.
Electronegativity exceptions flip the usual rules
Oxygen and chlorine typically act as −2 and −1, but fluorine and special compounds (peroxides, superoxide, OF2) alter electron distribution, creating unusual oxidation numbers.
