A2 molecule is considered in a simple way as two touching A atoms as depicted in the Figure. Does this arrangement have a lower energy than two separated A atoms? The radius r. of the A atom is 0.1 nm. Using the Virial Theorem, consider the following: a. Calculate the total electrostatic potential energy (PE) of all the charges when they are arranged as shown in Figure. Is this configuration energetically favorable? b. Given that in the isolated A-atom the PE is 2 ×(-15 eV), calculate the change in PE in going from two isolated A-atoms to the A2 molecule. Using the Virial theorem, find the change in the total energy. Nucleus Nucleus e---
