How is the number of valence electrons related to the ionization energy of an element? (1 point) low ionization energy correlates to elements with fewer valence electrons. elements with higher ionization energy tend to have less valence electrons. atoms with nearly full valence electron shells have lower ionization energy. high ionization energy indicates a low likelihood to gain valence electrons.

High ionization energy indicates a low likelihood to gain valence electrons.

Explanation: Ionization energy is the energy required to remove the most loosely bound electron from an gaseous atom.

Thus atoms with smaller radii will have high ionization energies as the electrons are tightly held by the nucleus.

Moreover the atoms with half or fully filled configurations are stable , so high energy is required to remove the electron.Thus they have high value of ionization energy.  And there is less likelihood for them to gain electrons as that would make them unstable.
