Question

why lithium is the strongest reducing agent?

Answer 1

electrongetativity value. Also, think of the available valence electrons and where they're at.

Answer 2

Li has a very low ionization potential, it "wants" to lose that one electron.

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.

remember, Li is the strongest reducing agent

Answer 3

I think Cs is also a strong reducing agent and very efficient in synthesis.

Answer 4

but i suppose that cesium is more easily oxidised in comparison to lithium
