The reactivity of non-metals decreases down the group due to increases in the number of valence shells. Consequently, platinum is often found chemically uncombined as native platinum. The metals with high reactive series in the above table also indicates that reverse reaction is a bit tough process. Metals that exist in the form of salts have already lost their electrons and therefore are no longer reactive. The relative reactivity of different metals can be seen on the reactivity of metals chart. You must know the order of reactivity of the metals as shown in the diagram below: Potassium is the most reactive metal on the reactivity series and gold is the least reactive metal.
