Electron Shells[edit]

Uranium has a high number of electrons; this diagram shows how they are arranged.
An electron shell is a group of atomic orbitals with the same value of the principal quantum number n. Electron shells are made up of one or more electron subshells, or sublevels, which have two or more orbitals with the same angular momentum quantum number l. Electron shells make up the electron configuration of an atom. It can be shown that the number of electrons that can reside in a shell is equal to .

This peer review is for a set of images, the entirety of which can be found here. While any one alone is obviously unworthy of featured status, together, the clarity that they demonstrate the concept of the electron shell (stemming from simplicity) may be worth "featured set" status. The set is comprehensive and uniform; they are all SVGs; the author for all of them is Pumbaa (original work by Greg Robson); they are all under the same acceptable license. Most do not appear in any article, but the sodium image appears in electron shell and neon appears in noble gas. I put up Uranium because it's a fairly well known element that has a high number of electrons; hydrogen makes a more natural "lead" image. There's not really much that can be done to improve these images, especially on the scale of over 100 images, without losing the simplicity. Such, I only want to gauge the community's reaction.--HereToHelp 13:21, 16 March 2007 (UTC)Reply[reply]


  • Wow, I'm really impressed with this set -- good find. I especially like the periodic table form of the set. That said, I think some of the scientist types might complain that this way of displaying them distorts the true size of the electron shell and the nucleus, relative to one another (as is already pointed out in the caption, I believe). I don't know how that would affect nomination, since there is no realistic way to fit them all if they were to scale. Still, I think with that caveat made clear, it might have a shot at FP. Any other physics people have suggestions? --Asiir 02:59, 17 March 2007 (UTC)Reply[reply]
  • I like the periodic table version too, but it's not an SVG. But it is 7022 × 4967, which is big enough to make a poster out of. So close enough. Also, it shows the nucleus as a circle, rather than a clump of neutrons and protons. But the nucleus isn't what's being focused on, so it's passable.--HereToHelp 17:02, 17 March 2007 (UTC)Reply[reply]
