Web13 aug. 2024 · E ( g) → E + ( g) + e − energy required=I. Because an input of energy is required, the ionization energy is always positive ( I > 0) for the reaction as written in Equation 4.4.1. Larger values of I mean that the electron is more tightly bound to the atom and harder to remove. Typical units for ionization energies are kilojoules/mole (kJ ...
WebThe energy required to remove the third electron is the third ionization energy, and so on. Energy is always required to remove electrons from atoms or ions, so ionization processes are endothermic and IE values are always positive. For larger atoms, the most loosely bound electron is located farther from the nucleus and so is easier to remove.
