lonization energy (E;) is the amount of energy required to remove anelectron from a neutral gaseous atom or gaseous ion. Electrons areattracted to the positively charged nucleus; therefore removing anelectron requires energy. The process is endothermic, and soionization energies have a positive value. The first ionization energy (En) is the energy associated with the removal of an electron from theneutral gaseous atom. The reaction is represented for the generalizedatom X asX X +eThe amount of energy required to remove an electron is related to theeffective nuclear charge and the stability of the electron configurationof the atom. It therefore shows periodic variation generally increasingfrom left to right in a period and from bottom to top of a group. Ingeneral, metals have lower Ei1 values than nonmetals. Exceptions tothis general trend from left to right occur when a completely filled ssubshell or half-filled p subshell is encountered. These stableconfigurations have larger than expected En values.
