Question

How can we relate reduction potential and reactivity?

Answer 1

In case of non metals, More the S. R. P of element, more it has power to undergo reduction(oxidise others) . More it is reactive.. Like halogens.. They have highest SRP..

And

In case of metals, more the value of SOP, more it has power to undergo oxidation (reduce other).. Like alkali metals. Li, Na, k etc
