Shit makes no sense.

 >> Intuitive understanding of electron orbital models  Anonymous Fri Jul 8 22:05:16 2016 No.8192493 [View] File: 148 KB, 1404x824, orbits.jpg [View same] [iqdb] [saucenao] [google] [report] I'm trying to learn more basic physical chem and I've never been satisfied with the explanations given for pic-related representations of electron orbitals.What does the 3-D surface represent? Is that some particular spatial probability density for finding an electron there, and if so what is that density? And what is meant by the opposite lobe of a p-orbital having this "negative" potential; how can it have negative probability density?Also, e.g. for s-orbitals the density seems to peak at the nucleon location -- is it actually possible to find an electron right in the middle of the nucleus?Finally how do energy levels modulate each orbital type? Are the lobes the exact same shape but expand farther out in space? Or are they somehow offset some distance from the nucleon and within that spherical shell, there can be no electron with that higher energy state? Or maybe still, they occupy exactly the same space but have higher momenta? The traditional model seems to imply that energy levels have "distinct" orbital regions, but from these model representations I can't see how that's possible unless they just overlap in space.Thanks in advance

Especially sites that go in depth into interesting topics/ are stimulating to read every now and again.

I'm self-studying Chemistry before I take my Gen Chem I course in college and one of my personal hangups that I've had since high school Chemistry is how could I visualize how the electrons are behaving in these bubble orbitals.I remember in 7th grade physical science class, the Bohr model made so much sense because I could picture the electrons around the nucleus of an atom just like the planets around the sun and in turn visualize how electrons would be shared. But now I don't have a clue because of the odd shapes that the orbitals entail. I've got a book I've been studying but in short, it just says that the shapes were derived from the Schrodinger equation and it "just is." If I could see an in-motion artist's rendition, my mental block of how the electron orbitals even work would be lifted and I could move on in the material. My main question primarily I want answered by watching an in-motion video I guess would be, since we can never know the position of an electron but only the probability of where it might be by the Heisenberg Uncertainty Principle, where is the electron most probable in a sense? Is it most probable in the outline shape of the orbital, in the center of the shape, or what?
