Chemistry Chapter 8 - Chemical Composition and Reactions

Oxidation Numbers

a number that represents the number of electrons that an atom in a compound must gain or lose to return to a neutral electrical state.

Oxidation Balancing Rule 1 - “Free element rule”

oxidation balancing rule - The number of atoms in natural forms and pure elements is zero

Oxidation Balancing Rule 2 - “ion rule”

oxidation balancing rule - oxidation number of monatomic ion is equal to ion’s charge

Oxidation Balancing Rule 3 - “zero-sum rule”

oxidation balancing rule - all oxidation numbers in a compound must add up to zero

Oxidation Balancing Rule 4 - “specific oxidation number rule“

oxidation balancing rule - certain elements regularly have the same oxidation numbers in compounds

Oxidation Balancing Rule 5

oxidation numbers of all atoms in a polyatomic ion add up to its charge
