A hydrogen-like ion is an ion containing only one electron. The energy of the electron in a hydrogen-like ion is given by:

En=-(2.18x10^(-18)J)Z^2(1/(n^2))

where n is the principal quantum number and Z is the atomic number of the element.

Calculate the ionization energy (in kJ/mol) of the He+ ion.
