WebJul 3, 2024 · Ionization energy exhibits periodicity on the periodic table. The general trend is for ionization energy to increase moving from left to right across an element period. Moving left to right across a period, atomic radius decreases, so electrons are more attracted to the (closer) nucleus. WebThe atomic radius increases as we move down any one group of the periodic table because elements have more electron shells if they are closer to the bottom of the periodic table. The outer shell of electrons ends up being farther from the atomic nucleus as we move down any one column of the periodic table. grand sichuan restaurant chelseaWebAs electron cloud sizes increase, so do atomic radii.
