There are many schemes to organize books: alphabetical order, by author, or even by color.
This Equation Bookshelf by estúdio breder, however, lets you to organize your books according to a criterion we don't normally associate with an organization scheme: their relative importance!
'Equation Bookshelf' is a simple idea of to divide things in priority order... put together the books that you need immediately or more important between (parentheses)! Set others between [square brackets] and {braces}.
Maybe today a beautiful flowerpot will be the most important thing! Tomorrow a portrait of a girlfriend and so on... A different and funny way to organize your objects!

Only the first one can be found in an hydrogen atom, because it only has one electron. And you need two electrons per orbital.
Each line in the periodic table adds another set of orbitals, in the following order: 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f, etc...
All of these plots are for hydrogen alone; only the first one is the ground state. Larger atoms fill up more than one of those orbitals at a time.
P.S. #3 really don't get the purpose behind this post; it is not a lecture in physics -- it is a BATCH OF COOKIES
