The ionization energy of an atom is the minimum energy required to remove the most loosely bound electron from a single atom. Typically the closer the outermost electrons are to the nucleus of the atom, the higher the atoms ionization energy will be.

Ionization Energy

The ionization energy refers to the amount of energy required to remove the most loosely bound electron from the species having a positive charge of . For example, the first three ionization energies are defined as follows:

• ionization energy is the energy that enables the reaction
• ionization energy is the energy that enables the reaction
• ionization energy is the energy that enables the reaction

Typically the ionization energy in a one electron system can be approximated using the ionization energy
