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. So if we graph energy versus our distance between them, we will see that a distance far apart, somewhere right here, we're going to have some energy. And as we begin moving them closer and closer, our energy will begin to decrease until we reach this point. And at this point, we have the minimum amount of energy.
