The energy needed to remove an electron from an atom (in the gaseous state) is called the IONIZATION ENERGY.

The energy required to remove an electron from a neutral atom is the atom's ionization energy. It represents the amount of energy needed to remove the most loosely bound electron from an atom in its gaseous state.
Yes, ionization energy is the energy required to remove an electron from a neutral atom. When an electron is added to a neutral atom, it is called electron affinity.
ionization energy
Ionization energy is the amount of energy required to remove one electron from a neutral atom in the gaseous state. It is a measure of how tightly the electron is held by the nucleus of the atom. Elements with higher ionization energies require more energy to remove an electron and are less likely to form ions.
The energy required to remove an electron from a gaseous atom is called the ionization energy. This energy depends on factors such as the atomic structure and the strength of the attraction between the nucleus and the electron. The higher the attraction, the higher the ionization energy needed to remove the electron.
