What is Reactivity series?
In introductory [[chemistry]], the '''reactivity series''' or '''activity series''' is an [[empiricism|empirical]] series of [[metal]]s, in order of [[chemical reactivity]] from highest to lowest. It is used to summarize information about the [[chemical reaction]]s 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 h {{chem-stub}} [[Category:Chemistry]]
