Why does ionization energy decrease down a group - AnswerData

WebGoing down the group, the first ionisation energy decreases. There is more shielding between the nucleus and the outer electrons and the distance between the nucleus and the outer electron increases and therefore the force of attraction between the nucleus and outer most electrons is reduced. WebIonisation enthalpy decreases from top to bottom in the group due to the increase in atomic size. 4.

How does ionization energy change down a group? - Vedantu

WebWhy does the First Ionisation Energy decrease down a group in the Periodic Table? Two major factors control how tightly held the outermost electron is and therefore how much energy is required to remove it, which gives us the size of the Ionisation energy. The first of these factors is shielding. WebThe size of the first ionisation energy is affected by four factors: \t; Size of the nuclear charge \t; Distance of outer electrons from the nucleus \t; Shielding effect of inner electrons \t; Spin-pair repulsion \t; First ionisation energy increases across a period and decreases down a group; A graph showing the ionisation energies of the ...
