{{Short description|Particle adsorbed onto the surface of a solid}}An '''adparticle''' is an atom, molecule, or cluster of atoms or molecules that lies on a crystal surface. The term is used in surface chemistry. The word is a contraction of "adsorbed particle". An adparticle that is a single atom may be referred to as an "adatom".<ref>{{Cite journal |date=1988 |editor-last=Grunze |editor-first=Michael |editor2-last=Weimer |editor2-first=Jeffrey J. |editor3-last=Kreuzer |editor3-first=Hans Jürgen |title=Diffusion at Interfaces: Microscopic Concepts |url=https://link.springer.com/book/10.1007/978-3-642-73632-2 |series=Springer Series in Surface Sciences |volume=12 |language=en |edition=1 |publisher=Springer Publishing |doi=10.1007/978-3-642-73632-2 |isbn=978-3-642-73634-6 |issn=0931-5195|url-access=subscription }}</ref>
