What Is Excitation Of Energy ?
Excitation: The energy needed to change something from the ground state to any particular excited state, the disturbed or altered condition resulting from stimulation of an individual, organ, tissue, or cell. Excitation is the movement of an electron from a lower energy level to a higher energy level by absorbing energy. It makes an atom move from a ground state to an excited state. Ionization energy is the removal of an electron from a neutral gaseous atom. The main difference between excitation and ionization potential is that excitationexplains the movement of an electron from a lower energy level to a higher energy level whereas ionization potential explains the complete removal of an electron from an energy level.
Ionization potential or ionization energy is the amount of energy required to remove the most loosely bound electron from a neutral, gaseous atom. This electron is a valence electron because it is the electron that resides farthest from the atomic nucleus. The ionization of a neutral atom causes the formation of a cation.
