The energy required to remove an electron from the outermost orbit of an atom is called ____ potential energy.

Question

Question

Answer 1

The correct answer is option 4 i.e., ionization.

The minimum energy required to remove an electron from the ground state of an atom in the gas phase is its ionization energy.
The magnitude of the ionization energy is a measure of how strongly the outermost electron is held by an atom.
For multiple electron atom, the energies required to remove a second and third electron are called second and third ionization energy respectively.

Types of Energy and their Uses

Types of Energy	Application
Excitation	To raise the electron from its ground state to the excited state
Induction	To produce an EMF across an electrical conductor
Radiation	Used in telecommunications, heating, radiometry etc.
Ionization	To remove an electron from the outermost orbit of an atom
