Consider an electron and a proton that are separated by 230 pm. What is the electrostatic potential energy (in joules) between an electron and a proton that are separated by 230 pm? What is the change in potential energy if the distance separating the electron and proton is increased to 1.0 nm? Does the potential energy of the two particles increase or decrease when the distance is increased to 1.0 nm? Using the result in c, conclude what happens to the energy of the system if the distance separating two oppositely charged particles (such as electrons and nuclei in chemical bonds) is increased.
