Problem 88

( Ill) A simple picture of an H2 molecule sharing two electronsis shown in Fig. 40-49. We assume the electrons aresymmetrically located between the two protons, which areseparated by r0 = 0.074 nm. (a) When the electrons areseparated by a distance d, write the total potential energy Uin terms of d and r0. (b) Make a graph of U in eV as a functionof d in nm, and state where U has a minimum on your graph, andfor what range of d values U is negative, (c) Determine analyticallythe value of d that gives minimum U (greatest stability).
