Web26 nov. 2024 · Ionization energy is lowest for the alkali metals which have a single electron outside a closed shell. Ionization energy increases across a row on the periodic maximum for the noble gases which have closed shells. For example, sodium requires only 496 kJ/mol or 5.14 eV/atom to ionize it. Web6 feb. 2024 · The first ionization energy of potassium is 419 kJ/mol while calcium’s is 376 kJ/mol. Note that the first ionization energy is the amount of energy needed to remove an outer electron from the atom. For calcium, we have a much larger atom because we have more electrons and the electrons are at energy levels farther from the nucleus.
