The very active metals react with water. For example, calcium reacts with water to form calcium hydroxide and hydrogen gas. Calcium metal has an oxidation nuer of 0, whereas Ca 2+ in Ca (OH) 2 has an oxidation nuer of +2, so calcium is oxidized. Hydrogen''s oxidation nuer changes from +1 to 0, so it is reduced.
