ChemicalEntity

A chemical entity comprises the two different ways to represents matter: as single recognizable particle entity (molecular entity) and as a composition of particle entities (substance). This distinction is not well assessed in actual chemical nomenclature, in which an element name refers to both the pure elemental substance or the atom. In the EMMO we force the adoption of a more strict categorization based on mereotopology. The class Material hosts the subclasses for which a substance can be identified without necessarily considering its nature of molecule/atom or substance (e.g. hydrocarbon is the class of both hydrocarbon molecules or gases).
