Reactivity series

In introductory chemistry, the reactivity series or activity series is an empirical series of metals, in order of chemical reactivity from highest to lowest. It is used to summarize information about the chemical reactions of metals with acids and water, single displacement reactions and the extraction of metals from their ores. The elements at a higher level are more reactive, whereas the elements at a lower level are less reactive.

The reactivity series reads as follows, starting at the most reactive, going down to the least reactive:

Cobalt Co
Nickel Ni
Tin Sn
Lead Pb
Hydrogen H
Antimony Sb
Bismuth Bi
Copper Cu
Tungsten W
Mercury Hg
Silver Ag
Gold Au
Platinum Pt
