WebFeb 20, 2014 · The 3d, 4d etc., can each hold ten electrons, because they each have five orbitals, and each orbital can hold two electrons (5*2=10). Thus, to find the number of electrons possible per shell First, we look at the n=1 shell (the first shell). It has: The 1s orbital An s-orbital holds 2 electrons. Thus n=1 shell can hold two electrons. WebThis need to gain a filled valance electron shell by having 8 valence electrons is known as the octet rule and explains why certain elements are stable or unstable despite being electrically neutral. This octet rule holds for elements in the second and third periods (or rows) of the periodic table.

WebApr 15, 2014 · Oct 7, 2014. Sodium has one valence electron. Valence electrons are electrons found in the outermost shell of an atom. The shell number representing the valence shell will differ depending on the atom in question. For sodium, which is in the 3rd row of the periodic table, the valence electrons will be found in the 3rd shell. WebAug 19, 2024 · The electron configuration of sodium is 1 s 2 2 s 2 2 p 6 3 s 1 (Table 2.7. 1 ).

But for most of the … 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… phoenix greens contact number
