WebThe quantum theory of the atom explains the eight electrons as a closed shell with an s 2 p 6 electron configuration. A closed-shell configuration is one in which low-lying energy levels are full and higher energy levels are empty. For example, the neon atom ground state has a full n = 2 shell (2s 2 2p 6) and an empty n = 3 shell. http://www.chem4kids.com/files/elements/026_shells.html

Using abbreviated electron configuration (or noble gas configuration) to identify valence electrons
WebNov 5, 2024 · Remember, the valence electrons are found in the outermost shell. The filling of the electron shells depends on their orbital. The first orbital (an s orbital) can contain only two electrons. Beryllium Greg … In chemistry and atomic physics, an electron shell may be thought of as an orbit followed by electrons 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 farther and farther from the nucleus. The shells correspond to the principal quantum numbers (n = 1, 2, 3, 4 ...) or are labeled alphabetically with the letters used in X-ray notation (K, L, M, ...). A usef…
WebAug 15, 2024 · An orbital can hold up to two electrons. So, the 0 th (s) subshell can hold 1 orbital, and thus two electrons. The 1 st subshell (p) can hold 3 orbitals, or 6 electrons. This is why we have the 2 n 2 rule. There are as many orbitals in the n shell as the sum of the first mathrm n odd numbers: n 2, and two electrons in each ( 2 n 2 ).
