The USBTypewriter™ is the must have computer accessory for us old school types.
Lovers of the look, feel, and quality of old fashioned manual typewriters can now use them as keyboards for any USB-capable computer, such as a PC, Mac, or even iPad! The modification is easy to install, it involves no messy wiring, and does not change the outward appearance of the typewriter.

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
