L'importanza scientifica e culturale del concetto, fondante per la chimica, di molecola è stato analizzato sia da un punto di vista storico sia da quello epistemologico. Tale concetto implica una visione del mondo materiale differenziato in entità strutturate/organizzate che sono i soggetti e gli oggetti della spiegazione chimica a livello microscopico, in stretto rapporto (ma non biunivoco) con la pluralità macroscopico delle sostanze pure. Nel rapporto tra il mondo microscopico e quello macroscopico vanno, infatti, inserite le interazioni tra molecole, con la formazione di "reti di molecole", entità intrinsecamente dinamiche. Dal confronto tra i concetti di molecola e di rete di molecole viene fuori l'importanza di una trattazione dinamica degli enti chimici, anche in ambito non strettamente reattivo.

Abstract
The scientific and cultural importance of the concept, fundamental for chemistry, of molecule has been analyzed both from a historical point of view and from the epistemological one. This concept implies a vision of the material world differentiated in entities structured/organized that are the subjects and objects of chemical explanation at the microscopic level, in close relationship (but not in a biunivocal way) with the macroscopic variety of pure substances. In the relationship between the microscopic and the macroscopic world must be considered, in fact, the interactions between molecules, with the formation of "networks of molecules", inherently dynamic entities. From the comparison between the concepts of molecule and network of molecules comes out the importance of a dynamic treatment of the chemical entities, even in non-strictly reactive sense.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
