The general formula is that the nth shell can in principle hold up to 2(n2) electrons.[1] For an explanation of why electrons exist in these shells, see electron configuration. [2] Each shell consists of one or more subshells, and each subshell consists of one or more atomic orbitals. History. Meer weergeven 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 … Meer weergeven Each shell is composed of one or more subshells, which are themselves composed of atomic orbitals. For example, the first (K) shell has one subshell, called 1s; the second (L) shell has two subshells, called 2s and 2p; the third shell has 3s, 3p, and 3d; the … Meer weergeven Although it is sometimes stated that all the electrons in a shell have the same energy, this is an approximation.
