Or

Description :
Or, avec le numéro de registre du Chemical Abstracts Service (CAS) 7440-57-5, est un élément métallique très apprécié connu pour sa couleur jaune distincte et son éclat. Il est classé comme un métal de transition et est représenté par le symbole Au dans le tableau périodique. Or se caractérise par sa grande malléabilité et ductilité, ce qui lui permet d'être facilement façonné en feuilles minces ou tiré en fils sans se casser. Il est également très résistant à la corrosion et à l'oxydation, ce qui le rend stable dans divers environnements. Or a une haute densité et est un bon conducteur d'électricité et de chaleur. Chimiquement, il est relativement inerte, ne réagissant qu'avec quelques substances, comme les halogènes et les cyanures, dans des conditions spécifiques. Or se trouve souvent dans la nature sous sa forme native, typiquement dans des dépôts alluviaux, et est couramment utilisé dans les bijoux, l'électronique et comme standard pour les systèmes monétaires en raison de sa valeur intrinsèque et de sa rareté. Ses propriétés uniques et son attrait esthétique en ont fait un symbole de richesse et de prestige à travers l'histoire.
