Mentioning reactivity series we are also required to know that metals above Zinc cannot be extracted by heating with Carbon, metals below Hydrogen does not react with acid to form salt and hydrogen, Copper does not react with steam and cold water, whereas Magnesium, Zinc and Iron only reacts with steam.
