WebThe ionization energy of the elements within a period generally increases from left to right. This is due to valence shell stability. The ionization energy of the elements within a group generally decreases from top to bottom. This is due to electron shielding. Why does ionization energy tend to increase as you move across a period quizlet? WebEnergy + AB →→ AB + e-. is called the ionization energy of the molecule or atom. How tightly an atom holds onto its electrons is measured by the ionization energy. The tighter an electron is held, the higher is its ionization energy. The developments in ionization energy are just the reverse of those for atomic radii.
