Helium electrons
WebThe helium ground state consists of two identical 1s electrons. The energy required to remove one of them is the highest ionization energyof any atom in the periodic table: 24.6 electron volts. The energy required to remove the second electron is 54.4 eV, as would be expected by modeling it after the hydrogen energy levels.
