Potential energy and internuclear distance

[QUOTE="blue_leaf77, post: 5938896, member: 536596"] You seem to be confusing energy with force. Conservative force like the one relevant in this case is equal to the gradient of potential energy. In the minimum of a potential energy curve, the gradient is zero and thus the net force is zero - the particles are stable. So, no, the molecules will not get closer and closer as it reaches equilibrium. It's not quite right to assign charges for the molecules in question because in fact that potential energy curve is not obtained using the usual electrostatic potential energy formula. It is obtained by solving Schroedinger equation for the electronic part of the total wavefunction of the two H atoms. It just happens that the ground state energy of H[SUB]2[/SUB] molecule so obtained takes a shape that resembles electrostatic potential energy. [/QUOTE]
