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.
