WebHelium Energy Levels The helium ground state consists of two identical 1s electrons. The energy required to remove one of them is the highest ionization energy of 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.The He+ … Web23 jul. 2016 · The notable exception is Helium, which was first discovered by its characteristic spectral lines in the light from the sun - at the time it was thought to have been a metal, hence the name (helios - sun, -ium - metal).
