High ionization energies

Web26 de nov. de 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. WebHowever, they only have the highest ionization energy in their period because they are the most stable elements. Moving down the noble gases group, the ionization energy decreases. So while you are right that in general, noble gases have high ionization energy, it is still easier to take an electron away from some noble gases than others.

The elements of the periodic table sorted by ionization energy

WebThe ionization energy of sodium is larger than the electron affinity of chlorine, so energy is required to remove an electron from a sodium atom and attach it to a chlorine atom. That is, at first sight it appears that the total energy of a Na + ion and a Cl − ion is greater than that of a sodium atom and a chlorine atom. Web6 de dez. de 2024 · Ionization energy is the minimum energy required to remove an electron from an atom or ion in the gas phase.
