To remove an electron in an atom, and then it becomes an ion's can provide a certain amount of energy is called ionization energy which is the minimum energy required to remove it from \\ to an electron and bring it to an infinite distance and which is measured in kilojoules per mole (kJ / mol) in kilocalories per mole (kcal / mol) or electron volts (eV). It depends on the atomic species. Naturally, the more the electrons are close to the nucleus (as in non-metals), the greater the amount of energy that must be given to remove the electrons from the atom. If
leaves the first outer electron from the atom, energy is called the first ionization energy. This posts a p electron, the second one detaches from the s sublayer full s. The third ionization energy of the electron is greater because, while the atom loses electrons, its nuclear charge is constant and the remaining electrons are held more firmly.
The fourth ionization energy is about four times the third.
