So, here we have a protons. We have a nucleus and protons inside that nucleus. And this is our one S orbital, our two S orbital and the two P orbital. So recall that as our electron gets closer and closer to our protons in the nucleus, the energy level of the entire atom decreases, so it becomes more stable. So the closer our electron is to our nucleus, the more stable that atom is. And let's look what happens when an acid, a brothed lauric acid, reacts.
