The outermost shell is called valence shell and it can never have more than 8 electrons in any atom.
Since each shell has a definite number of orbitals and each orbital occupies an electron pair, each shell has a maximum electron count (maximum occupancy). Electrons in an atom are identified using quantum numbers. Answer and Explanation: The allowed values of l, ml ...
