Rb : [kr] Rb++[Ar]4323d104p) b Why is the second ionization energy much greater than the first? Second ionization energy is always 4 times greater than the first. After removal of the second electron, rubidium has a configuration of noble gas. The second electron is removed from 4p, which is much closer to the nucleus than 58, Rb has a configuration of noble gas, which is stable. Submit What experiments could be done to provide some evidence that the correct formulation...

Ionization energy (Ei) is the amount of energy required to remove an electron from a neutral gaseous atom or gaseous ion. Electrons are attracted to the positively charged nucleus; therefore removing an electron requires energy. The process is endothermic, and so ionization energies have a positive value. The first ionization energy (Ei1) is the energy associated with the removal of an electron from the neutral gaseous atom. The reaction is represented for the generalized atom X as X→X++e− The amount...
