The work done in emitting the electron from an atom or a molecule is:
Correct answer: A. Ionization energy
- A. Ionization energy
- B. Excitation energy
- C. Excitation potential
- D. Ionization potential
Explanation
When an electron is emitted from an atom or a molecule, the energy required to remove the electron completely from its bound state is called the ionization energy. It represents the minimum amount of energy needed to overcome the attractive forces between the electron and the nucleus.As explained above, ionization energy is the correct term for the energy required to remove an electron from an atom or molecule. It is a fundamental concept in atomic and molecular physics.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
