We’re gift asked to calculate binding power of the electron in kJ/mol. When photons through enough energy hit the surface of a metal, electrons are emitted. This phenomenon is well-known as the Photoelectric Effect.

You are watching: What is the binding energy of the electron in kj/mol?

Total energy (ΔE) in photoelectric impact can be calculated utilizing the following equation:

∆E=Ework function+Ekinetic energy


ΔEisthetotal power or the energy of the light/photon/radiationand have the right to be calculated utilizing the equation:


Etotal power = Jh = Planck’s constant = 6.626x10-34 J∙sν= frequency = Hz or s-1

Ework functionisthework function or threshold frequency or binding energyof the metal (minimum energy required to remove an electron indigenous the metal)
