Each element is detailed with the name, symbol and number of electrons in each shell. The colour scheme is designed to match that used : 21:16, 1 April 2007: 4,213 × 2,980 (4.57 MB) GregRobson == Summary == * '''Description:''' Diagram showing the periodic table of elements in the form of their electron shells.
In chemistry and atomic physics, an electron shell may be thought of as an orbit that electrons follow around an atom's nucleus.The closest shell to the nucleus is called the "1 shell" (also called the "K shell"), followed by the "2 shell" (or "L shell"), then the "3 shell" (or "M shell"), and so on further and further from the nucleus.
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 2 n 2 {\displaystyle 2n^{2}} . This image combines all the diagrams into one SVG image, at the nominator's request.
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.
The 2s electron is lithium's only valence electron, as the 1s subshell is now too tightly bound to the nucleus to participate in chemical bonding to other atoms: such a shell is called a "core shell". The 1s subshell is a core shell for all elements from lithium onward. The 2s subshell is completed by the next element beryllium (1s 2 2s 2). The ...
