a This question uses He to explore the ability of one electron to shield another from the positive charge of the nucleus. The ionization of an atom not experiencing shielding can be calculated from Bohr's equation for the electron energy. E = −(N₁ Rhc) (Z² / n²) where N₁ Rhc = 1312 kJ/mol and Z is the atomic number. Use this approach to calculate a possible ionization energy for helium assuming the electrons of the He experience the full 2+ nuclear charge. This gives us the upper limit for the ionization energy. Ionization energy = kJ/mol

Question
a This question uses He to explore the ability of one electron to shield another from the positive charge of the nucleus. The ionization of an atom not experiencing shielding can be calculated from Bohr's equation for the electron energy. E = - (N₁Rhc) (Z²/n² where N₁ Rhc = 1312 kJ/mol and Z is the atomic number. Use this approach to calculate a possible ionization energy for helium assuming the electrons of the He experience the full 2+ nuclear charge. This gives us the upper limit for the ionization energy. Ionization energy = kJ/mol
