NDA General Science Chemistry Questions Part 2

This competition for release of electrons incidently remainds us of the competition for release of protons among acids. The similarity suggests that we might develop a table in which metals and their ions are listed on the basis of their tendency to release electrons just as we do in the case of acids to indicate the strength of the acids. As a matter of fact we have already made certain comparisons. By comparison we have come to know that zinc releases electrons to copper and copper releases electrons to silver and, therefore, the electron releasing tendency of the metals is in the order : Zn > Cu > Ag. We would love to make our list more vast and design a metal activity series or electro-chemical series.
