A proton and electron are far away from each other (infinite distance away from each other). Both the proton and electron are then brought together so they can form a hydrogen atom. The electron circles the proton at a distance of 5.29 x 10^-11 m. What is the EPE(final) - EPE (total), which is the change in the electron potential energy? Give answer in J and eV.
b. how quick would the electron be going in the orbit if we assume centripetal motion?Therefore, what is the electrnss kinetic energy?
c. what about the total energy of the electron in this orbit? Try to confirm this value: The ground state energy of a hydrogen atom
