I am a bit confused about what happens to the energy levels during an exothermic reaction.

I understand that during an exothermic reaction, the energy of the electrons decreases.

Is the potential energy of electrons related to the energy level diagram, shown below?

So if the potential energy decreases, does that mean the ground state for the new molecules formed will be different from the old molecules?

Yes, electron energy levels are like that, especially for single atoms.

Yes, forming molecular bonds creates different electron energy levels, with exothermic reactions leading to chemical bonds with lower ground levels then the reagents had.

  So when the exothermic reaction finishes, will the electrons end up at the ground energy level?

  Usually yes, even if sometimes they can even temporarily stay excited.
