# What are the five strongest reducing and oxidizing agents?

The most potent oxidant is undoubtedly the fluorine molecule. Dioxygen gas, is a less potent oxidant than fluorine, but still very fierce. Anyway, your question is quantifiable. And we could consult tables of standard electrode potentials, and come up with fluorine (which is screamingly hot), $C {o}^{3 +}$, $M n {O}_{4}^{-}$, $A {u}^{3 +}$, $C {l}_{2}$, and $M n {O}_{4}^{-}$. $C {l}_{2}$, like ${F}_{2}$ is an halogen, and from its late position on the Table, we would also expect it to be highly oxidizing. The other metals are in a high oxidation state, and are also expected to be strongly oxidizing.
