WebThe work function of a metal is the minimum amount of energy that will take out an electron from the orbital of an atom. The value of the work function is equal to the energy of the electron revolving around the nucleus. It is measured in electron volt (eV) Importance of Work Function WebThe work function is measured via the photoelectric effect, showing that long-term hydrogen plasma exposure results in a steady-state surface work function of 2.75±0.10 eV.
