Answer:
An electron shell[1] is the outside part of an atom around the atomic nucleus. It is where the electrons are, and is a group of atomic orbitals with the same value of the principal quantum number n.
Example of a sodium electron shell model which has three shells.
Explanation:
Electron shells have one or more electron sub-shells, or sub-levels. These sub-levels have two or more orbitals with the same angular momentum quantum number. Electron shells make up the electron configuration of an atom. The number of electrons that can be in a shell is equal to {\displaystyle 2n^{2}} {\displaystyle 2n^{2}}.
The name for electron shells comes from the Bohr model, in which groups of electrons were believed to go around the nucleus at certain distances, so that their orbits formed "shells". This term was presented by the Danish physicist Niels Henrik David Bohr.
