Use the uncertainty principle to estimate the binding energy of the H2 molecule by calculating the difference in kinetic energy of the electrons between (i) when they are in separate atoms and (ii) when they are in the molecule. Take ∆x for the electrons in the separated atoms to be the radius of the first Bohr orbit, 0.053 nm, and for the molecule take ∆x to be the separation of the nuclei, 0.074 nm.
