Gold is least reactive with aqueous solutions of metal ions among tin, zinc, gold, and calcium. Gold is a noble metal and does not readily react with most common reagents, including aqueous solutions of metal ions.
Metals which can easily loose electron are most reactive. They are present in group-1.
fluorine is the most reactive non metal in the periodic table.
Francium (Fr) is the most reactive metal.
