SUMMARY
The potential energy of two atoms is defined by the equation U(r) = -4Uo[(Ro/r)^12 - (Ro/r)^6]. To find the radius at stable equilibrium, the force equation F(r) = -dU(r)/dr is set to zero. The work required to separate the two atoms is determined by calculating the difference in potential energy between the equilibrium position and the state where the atoms are infinitely apart. The potential energy at infinite separation is zero, making the work equal to the negative of the potential energy at the equilibrium radius.
