The word "nucleus" is from 1704, meaning “kernel of a nut”. In 1844, Michael Faraday used nucleus to describe the “central point of an atom”. The modern atomic meaning was proposed by Ernest Rutherford in 1912. The use of the word "nucleus" in atomic theory, however, did not happen immediately. In 1916, for example, Gilbert N. Lewis wrote in his famous article "The Atom and the Molecule" that "the atom is composed of the "kernel" and an outer atom or "shell"".
