Anomalous trends in ionization energy - Chemistry Stack Exchange
WebExplanation Going down group 2: there are more filled shells between the nucleus and the outer electrons … the outer electrons are more shielded from the attraction of the nucleus … the distance between the nucleus and the outer … Web3 jun. 2015 · The main factor affecting ionizing energy (IE) is the attraction between the nucleus and the electrons. The more the attraction, the more energy is needed to remove an electron from it's orbital and hence higher the IE. The other factors modify this main factor and thus change the expected IE values to the anomalous observed values. Web14 nov. 2024 · Though the increase in ionization energy is found across the period in periodic table but exceptions are with decrease in ionization energy across the period 2 and 3 between groups 2 and 3, and 5 and 6 elements (Be>B, Mg>Al, N>O and P>S). Decrease from beryllium to boron. This can be explained by the electronic configuration … sign in divorce online
