ionization potentialor ionization energyAmount of energy required to remove an electron from an isolated atom or molecule. There is an ionization potential for each successive electron removed, though that associated with removing the first (most loosely held) electron is most commonly used. The ionization potential of an element is a measure of its ability to enter into chemical reactions requiring ion formation or donation of electrons and is related to the nature of the chemical bonding in the compounds formed by elements. See also binding energy, ionization. ionization energy [‚ī·ə·nə′zā·shən ¦en·ər·jē] (atomic physics) The amount of energy needed to remove an electron from a given kind of atom or molecule to an infinite distance; usually expressed in electron volts, and numerically equal to the ionization potential in volts.

| Moreover, the model also assumes-erroneously--that all energy transfers from the incident electron to the target molecule that exceed the ionization energy of a given molecular orbital result in ionization. |
