Atoms with one electron can be modeled with an equation similar to the Bohr equation:

E_{a} = -2.179x10^{-18} J (Z^{2}/n^{2})

In the equation, Z is the nuclear charge and n is the shell in which the electron resides. What is the ionization energy of Li^{2+}, assuming its electron is originally in the n=1 level?

A. 984.1 kJ/mol

B. 1312 kJ/mol

C. 495 kJ/mol

D. 3937 kJ/mol

E. 2953 kJ/mol
