EtymologyEdit

Borrowed from Latin nucleus (kernel, core), a diminutive of nux (nut). The earliest uses refer to the head of a comet and the kernel of a seed, both recorded in Lexicon Technicum in 1704. The sense in atomic physics was coined by English scientist Michael Faraday in 1844 in a theoretical meaning.
