What is Activity Series?
The activity series (also called the reactivity series) is a list of metals arranged in decreasing order of their chemical reactivity. A more active metal can displace a less active metal from its salt solution. The series determines which single displacement reactions will occur and is related to the standard electrode potential (E°) values of the metals.

The activity series (also called the reactivity series) is a list of metals arranged in decreasing order of their chemical reactivity. A more active metal can displace a less active metal from its salt solution. The series determines which single displacement reactions will occur and is related to the standard electrode potential (E°) values of the metals.
Predicting whether displacement reactions will occur; selecting metals for galvanic cells; choosing sacrificial anodes for cathodic protection; metallurgy and metal extraction (more reactive metals used to extract less reactive ones)
More reactive metals are more hazardous — alkali and alkaline earth metals react violently with water. Consult the SDS for specific metals. Handling reactive metals requires exclusion of moisture and sometimes an inert atmosphere.
The formula or notation for Activity Series is: Reactivity: K > Na > Ca > Mg > Al > Zn > Fe > Ni > Sn > Pb > H > Cu > Ag > Au
