High ionization energies
Web25 de jul. de 2024 · Re: Noble Gases Because noble gases have a full octet, their ionization energies are actually quite high. Electron affinity is the amount of energy released when an electron is added to a neutral atom. Because noble gases have stable electron configurations, they have very low electron affinities.

WebYes, it has a higher ionization energy. Cations are also smaller than the neutral atom, and the reason for both is the same. The positive charge in the core stays the same, if you … WebAboutTranscript. An element's second ionization energy is the energy required to remove the outermost, or least bound, electron from a 1+ ion of the element. Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first. Created by Jay. Sort by:
