And that's exactly why we see that as we go past 0.7 atroms, our energy begins to increase. So as you bring atoms closer and closer, repulsion of the positively charged nuclei causes a sharp increase in energy, as we see here. So as they're moving closer past the distance, the electrons, as well, as protons begin to repel one another, and the energy dramatically increases once again. To recap, nature likes to form stabilizing structures. Nature will not form a structure that is higher in energy. In other words, if this was higher in energy than this, this molecule would not form.
