The minimum energy needed to eject an electron from an atom is called its ionization energy I. In atomic physics, I is usually measured in electron-Volts (eV), with 1 eV being the energy needed to move a charge of 1 e across an electrostatic potential difference of 1 V, 1 eV = 1.602 x 10-19 CX1V -1.602 x 10-19 J. For the hydrogen atom | = 13.60 eV. If a photon ejects an electron with kinetic energy 5.0 eV from...
