2.19 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 , and the electron is roughly 1 from each proton. Determine the potential energy of the system. Specify your choice of the zero of potential energy.
Given,
Distance between proton 1 and 2
Distance between proton 1 and electron
Distance between proton 2 and electron
Now,
The potential energy of the system :
Substituting the values, we get
