Answer 1

Low ionization energies are most characteristic of atoms that are metals, I believe.

Answer 2

Answer:

Low ionization energies are most characteristic of atoms that are Metals

Explanation:

Metals tend to lose electrons in chemical reactions, as indicated by their low ionization energies. Ionization energy is the quantity of energy that an isolated, gaseous atom in the ground electronic state must absorb to discharge an electron, resulting in a cation. In metals the valence electrons are farther away from the positively charge nucleus, so the force of attraction is low therefore metals have low ionization energy.
