Science / Chemistry / Oxidation Number: A convention for representing a charge of an atom embedded within a compound, if the compound were purely ionic. For example, H2O is a covalent compound; if it were ionic, the hydrogens would be H+ (oxidation number +1) and the oxygen would be O2- (oxidation number -2). Oxidation number rises for at least one atom in a compound that is oxidized; oxidation number becomes smaller if the compound is reduced.

Science / Chemistry / Oxidation Half Reaction: That part of a redox reaction that involves loss of electrons. In the oxidation half reaction, the oxidation number of one or more atoms within the reactants is increased. MORE
Science / Biology / Oxidation: The loss of electrons from the outer shell of an atom; often accompanied by the transfer of a proton and thus involves the loss of a hydrogen ion. The loss of electrons or hydrogens in a chemical reac MORE
