An element's second ionization energy is the energy required to remove the outermost, or least bound, electron from a 1+ ion of the element. Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first. Created by Jay. Sort by:

WebMay 1, 2024 · The amount of positive charge experienced by any individual electron is the effective nuclear charge (Zeff). **. For example, in lithium (Li), none of the three electrons "feel" the full +3 charge from the nucleus (see Cartoon). Rather, each electron "feels" a Zeff that is less than the actual Z and that depends on the electron's orbital. WebTo find the electron configuration for an ion, first identify the configuration for the neutral atom. Then, add or remove electrons depending on the ion's charge. For example, to find the configuration for the lithium ion (Li⁺), start with neutral lithium (1s²2s¹). Then, since the lithium ion has one less electron, remove an electron from ...
WebThe number of electrons is the same but the number of protons (and the effective nuclear charge) increases in the order A r < K + < C a 2 +. Since argon has fully filled shells, it will have high electron-electron repulsions in its shell.
