The second ionization energyis … WebOn the periodic table, first ionization energy generally decreases as you move down a group. This is because the outermost electron is, on average, farther from the nucleus, meaning it is held less tightly and requires less energy to remove. Created by Jay. Sort by: Top Voted Questions Tips & Thanks Want to join the conversation? pishylu WebThe ionization energy of the elements increases as one moves up a given group because the electrons are held in lower-energy orbitals, closer to the nucleus and thus more tightly bound (harder to remove). Based on these two principles, the easiest element to ionize is francium and the hardest to ionize is helium. bing screensaver background today

WebApr 15, 2015 · From what I understand, in a stepwise ionization process, it is always the highest-energy electron (the one bound least tightly) that is removed first. So when we go more to the right in the periodic table, there are more electrons, and thus much more possibility for these to shield the outer electron from attraction to the nucleus.
