Question

If there is less ionization energy does that mean that it is more reactive? Why?

Answer 1

Answer:

The greater the ionization energy, the more difficult it is to remove an electron. The ionization energy may be an indicator of the reactivity of an element. Elements with a low ionization energy tend to be reducing agents and form cations, which in turn combine with anions to form salts.

Answer 2

yes, because when there is less ionization energy it means that the atomic radius is big so, it will be easy to steal electrons from the outer most orbit of the atom.
