pls answer both a & b and i would like the answer hand written as opposed to text

3A) The first ionization energy (IE 1 ) is the amount of energy required to move the electron out of the atom completely (from n=1 to n=). Use the Bohr equation and prove that the IE1=1310kJ/mol. [Note that the Bohr equation is the energy for a single atom.] [5] ENom=2.181018J(n2Z2) where Z= atomic number 3B) Use the Bohr equation and calculate the energy needed to remove the second clectron from He+(Z=2) in kJ/mol. The He+cation has two protons and one electron. Why isn't the IE simply twice the energy as hydrogen? Explain. [5]
