What does it mean if the ionization energy is high or low?

WebA high ionization energy means that a great deal of energy is needed to remove an electron. A low electron affinity means that little energy is given off when the atom acquires an electron. Many elements have low electron affinities because there is essentially no place to put an electron, as when an energy level is filled, as for the inert gases. Web22 de set. de 2015 · Sep 22, 2015. Due to the fact that they already have filled energy levels and zero valence electrons so they are very stable and do not readily want to give up their electrons in chemical reactions as this would then leave them more unstable again. By definition, ionization energy is the amount of energy required to release an electron … phobia history https://labottegadeldiavolo.com
