Question

Among alkali metals negative electrode potential of lithium is highest or lowest ?

Answer 1

lowest as because it is non metal the electonegative charge is only highest in metal

Answer 2

Among the alkali metals, lithium has the lowest negative electrode potential.

Explanation:

• In the periodic table group, 1 element is called alkali metals and it includes Lithium, Sodium, Potassium, Rubidium, Caesium, and Francium.
• The negative electrode potential value of all the alkali metals are as follows:

1. Lithium: -3.04
2. Sodium: - 2.714
3. Potassium: -2.925
4. Rubidium: -2.930
5. Caesium: - 2.927

• From the above values as lithium has -3.04 which is lowest when compared with other elements in the series, it is considered to have the lowest negative electrode potential.
