Question

How is the number of valence electrons related to the ionization energy of an element?

A) low ionization energy correlates to elements with fewer valence electrons
B) elements with higher ionization energy tend to have less valence electrons
C) atoms with nearly full valence electrons shells have lowers ionization energy
D) high ionization energy indicated a low likelihood to gain valence electrons

Answer 1

The number of valence electrons is related to the ionization energy of an element such that when there is few valence electrons, the ionization energy of an element is lower. The trend on the periodic table follows that the ionization energy fairly increases as the number of valence electron increases. Therefore the correct answer is letter "A."
