So, when I have these two protons a certain distance apart, the repulsion between these two protons going this way will equal the attraction of these electrons. In other words, this proton of H atom one will attract the electron of H atom two. And likewise, H atom two will attract the electron of H atom one. And in fact, when there are 0.7
angstromes, angstrom simply means one times ten to the negative 10 meters apart. When they're this distance apart, a bond will form, a covalent bond will form. And in fact, as you move the two H atoms closer and closer from a far distance apart, energy begins to decrease until we reach this point, until we reach 0.7
angstromes away.
