Question

lithium metal is the strongest reducing agent while lithium positive ion is the weakest ..........​

Answer 1

Answer:

Lithium is the strongest. Lithium has the lowest standard reduction potential, meaning that it is the easiest to become oxidized. When something is oxidized, it reduces another substance, becoming a reducing agent. Hence lithium is the strongest reducing agent.Lithium has most negative E°value but its reaction with water is less vigrous. ... This is because although lithium has a high Electrode potential, its hydration energy is very low due to which its is not soluble in water.

Answer 2

Answer:

Ionization energy in a group of the periodic table decreases from top to bottom. Lithium is the top most element in group -1(alkali metals). Thus, lithium has the highest ionization energy and the weakest reducing agent while Cs is the strongest reducing agent amongst alkali metals in a free gaseous state.
