The tendency of an electrode to lose electrons is known as

Given that the standard potentials $(E^{\circ})$ of $Cu^{2+}/Cu$ and $Cu^{+}/Cu$ are $0.34 \ V$ and $0.522 \ V$ respectively,the $E^{\circ}$ of $Cu^{2+}/Cu^{+}$ is (in $V$)

$K, Ca$ and $Li$ metals may be arranged in the decreasing order of their standard electrode potentials as

The reducing ability of the metals $K$,$Au$,$Zn$ and $Pb$ follows the order

$K,$ $Ca,$ and $Li$ metals may be arranged in the increasing order of their standard electrode potentials as
