Web12 apr. 2024 · The ionization energy of a chemical element, expressed in joules or electron volts, is usually measured in an electric discharge tube in which a fast-moving electron … 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.
