3A) The first ionization energy (IE₁) is the amount of energy required to move the electron out of the atom completely (from n=1 to n = ∞o). Use the Bohr equation and prove that the IE₁ = 1310 kJ/mol. [Note that the Bohr equation is the energy for a single atom.] [5] EA-2.18x10-18 J where Z atomic number 3B) Use the Bohr equation and calculate the energy needed to remove the second electron from He* (2-2) in kJ/mol. The He* cation has two protons and one electron. Why isn't the IE2 simply twice the energy as hydrogen? Explain.
