Each shell can contain only a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.[1] See more 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 … See more Each shell is composed of one or more subshells, which are themselves composed of atomic orbitals. For example, the first (K) shell has … See more Although it is sometimes stated that all the electrons in a shell have the same energy, this is an approximation.
