Question

Which element from the following has the highest negative standard reduction potential?

Options

• K

• Li

• Na

• Rb

Answer 1

Li

Explanation:

The alkali metal lithium has the lowest ionisation enthalpy of all the metals. It has a strong inclination to remove the electron from the valence shell, a weak tendency to accept electrons, and a preference for going through oxidation. Thus, it has the lowest standard reduction potential or highest negative standard reduction potential.
