When a specie undergoes oxidation, its
oxidation number increases
oxidation number decreases
oxidation number remains constant
acts as oxidizing agent
Explication
Oxidation is a chemical reaction that occurs when the oxidation number of an atom increases. This means that the atom loses electrons and has a greater positive charge or a lesser negative charge. The oxidation number of an atom is a number that represents the degree of oxidation of the atom in a chemical compound.
