If one of the two electrons of a H2, molecule is removed, we get a hydrogen molecular ion  In the ground state of an , 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.  

Answer:

Using P.E.=  for each pair of charges then adding up, we get the total P.E.                                                 = ?19.2 eV.                 Zero of P.E. is taken as infinity.
