If one of the two electrons of a H₂ molecule is removed, we get a hydrogen molecular ion H₂+. In the ground state of an H₂+, the two protons are separated by roughly 1.5 Å, and the electron is roughly 1 Å from each proton. Determine the potential energy of the system. Specify your choice of the zero of potential energy.
