What is the $emf$ series?

(N/A) The $emf$ series,also known as the $Electrochemical$ $Series$,is an arrangement of various electrodes or half-cells in the increasing order of their standard reduction potentials $(E^{\circ})$.
In this series,elements with more negative standard reduction potentials are placed at the top (stronger reducing agents),while those with more positive standard reduction potentials are placed at the bottom (stronger oxidizing agents).
This series helps in predicting the feasibility of redox reactions and calculating the standard cell potential $(E^{\circ}_{cell})$.
