Question

define excitation energy binding energy and ionization energy of an electron in an atom​

Answer 1

Answer:

The minimum energy required to excite an electron from the ground state of an atom to any excited state is called excitation energy. ... The potential difference through which the extra electron is to be acceleration in order for it to cause the ionization of an atom is called the ionization potential of the atom.

Answer 2

Explanation:

(1) Excitation energy of an electron in an atom : The energy required to transfer an electron from the ground state to an excited state (a state of higher energy) is called the excitation energy of the electron in that state.

(2) Binding energy of an electron in an atom is defined as the minimum energy that should be provided to an orbital electron to remove it from the atom such that its total energy is zero.

(3) Ionization energy of an electron in an atom is defined as the minimum energy required to remove the least strongly bound electron from a neutral atom such that its total energy is zero.
