A '''molecule''' {{IPAc-en|ˈ|m|ɒ|l|ɪ|k|juː|l}} is an electrically neutral group of two or more [[atom]]s held together by [[chemical bond]]s.<ref name="iupac">{{GoldBookRef|title=molecule|url=http://goldbook.iupac.org/M04002.html|year=1994}}</ref><ref>{{cite book| last = Puling| first = Linus| title = General Chemistry| year = 1970| publisher = Dover Publications, Inc.| location = New York| isbn = 0-486-65622-5 }}</ref><ref>{{cite book| author = Ebbin, Darrell, D.| title = General Chemistry, 3rd Ed.| year = 1990| publisher = Houghton Mifflin Co.| location = Boston| isbn = 0-395-43302-9 }}</ref><ref>{{cite book| author = Brown, T.L.| coauthors = Kenneth C.

However, in [[quantum physics]], [[organic chemistry]], and [[biochemistry]], the term ''molecule'' is often used less strictly, also being applied to [[polyatomic ion]]s.
