Metal stress series

Electrochemical stress series of metals are chemical elements arranged in order of decreasing chemical activity, which is equivalent to an increase in standard electrochemical potentials.

The metal cation reduction reaction in general looks like this:

Meⁿ⁺ + n·ē → Me⁰
Where, Me is metal. The reaction requires "n"electrons
