Question

Define the term first ionization energy

Answer 1

The ionization energy is a measure of the energy required to remove one electron from one mole of gaseous atoms or ions. It can be schematically expressed as follows:

X+IE →X^+ + e^-

The units of ionization energy are usually kJ/mol or kcal/mol.
The term ionization potential is an older name for ionization energy.
