Detailed explanation-1: -Ionization energy is correlated with the strength of attraction between the positively-charged nucleus and the negatively-charged valence electrons. The higher the ionization energy, the stronger the attractive force between nucleus and valence electrons, and the more energy is required to remove a valence electron.

Detailed explanation-2: -Factors Governing Ionization Energy Normally, when the ionization energy is high it will be more difficult to remove an electron.

Detailed explanation-3: -It is easier to remove electrons from atoms with a small ionization energy, so they will form cations more often in chemical reactions. Metals tend to have a smaller ionization energy, and alkali metals (with their single valence electron) have the lowest ionization energy as a group.

Detailed explanation-4: -ionization energy, also called ionization potential, in chemistry and physics, the amount of energy required to remove an electron from an isolated atom or molecule.

Detailed explanation-5: -1) As we go farther from the nucleus, the energy of orbitals increase. Also, the farther an electron is from the nucleus, the more repulsions it has to face because of other electrons(more screening effect) and hence it is easier to remove that electron.
