If one of the two electrons of a `H_(2)` molecule is removed, we get a hydrogen molecular ion `H_(2)^(+)`.In the ground state of an `H_(2)^(+)` , 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

Explanation

`-19.2 eV`, the zero of potential energy is taken to be at infinity
