:Ruthénium
Description :
Ruthénium est un métal de transition rare appartenant au groupe du platine, caractérisé par son apparence argentée et sa haute densité. Il est désigné par le symbole chimique Ru et a un numéro atomique de 44. Ruthénium est connu pour sa remarquable résistance à la corrosion et à l'oxydation, ce qui le rend stable dans divers environnements. Il présente plusieurs états d'oxydation, généralement compris entre -2 et +8, avec +3 et +4 étant les plus courants dans les composés. Ruthénium est souvent utilisé comme catalyseur dans les réactions chimiques, en particulier dans la production d'ammoniac et dans diverses transformations organiques. De plus, il trouve des applications dans l'électronique, notamment dans la fabrication de disques durs et de contacts électriques en raison de sa conductivité exceptionnelle. Les composés de Ruthénium peuvent également présenter des propriétés intéressantes, telles qu'une activité photomoléculaire et un potentiel d'utilisation dans des applications médicinales. Dans l'ensemble, les propriétés uniques et la polyvalence de Ruthénium en font un élément important tant dans les environnements industriels que de recherche.
