Reactivity Series

Some metals like sodium is highly reactive. Sodium reacts vigorously even with cold water producing hydrogen. Some metals like iron is less reactive. Iron will get rust in the presence of water and air and it will take weeks. Some metals like gold is not reactive at all. Order of the reactivity of metals is very important to make predictions of their reactivities and several other information. When the metals are ordered according to their reactivities it is called ' reactivity series'.

Arranging the metals in the reactivity series has done looking at their reactivities such as reaction with air, water, displacement reactions etc.

Order of the metals in the reactivity series can be given as follows.

K (pottasium)
Na (Sodium)
Ca (Calcium)
Mg (Magnesium)
Al (Aluminium)
Zn(Zinc)
Fe(Iron)
Sn (Tin)
Pd( lead)
(H)-(Hydrogen)
Cu (Copper)
Hg( Mercury)
Ag (silver)
Au (gold)
Pt (platinum)

Reactivity decreases down the reactivity series.

Hydrogen is not a metal . It has been included in the reactivity series to compare the reactivity of metals.
