CAS 7439-92-1: Plomb
Description :
Plomb, avec le numéro CAS 7439-92-1, est un métal lourd classé comme métal post-transition. Il est connu pour sa malléabilité, sa ductilité et son faible point de fusion, ce qui permet de le façonner et de le former facilement. Plomb a une couleur blanc-bleu lorsqu'il est fraîchement coupé, mais il ternit en un gris terne lorsqu'il est exposé à l'air en raison de la formation d'une couche d'oxyde. Il est relativement dense, avec un poids atomique élevé, et présente une mauvaise conductivité électrique par rapport à d'autres métaux. Plomb est également connu pour sa résistance à la corrosion, ce qui le rend utile dans diverses applications, y compris les batteries, le blindage contre les radiations et les matériaux de soudage. Cependant, Plomb est hautement toxique, en particulier pour le système nerveux, et peut causer de graves problèmes de santé en cas d'exposition, ce qui conduit à des réglementations strictes concernant son utilisation et son élimination. En termes de comportement chimique, Plomb peut former divers composés, y compris des oxydes, des sulfures et des halogénures, et présente généralement un état d'oxydation +2 dans la plupart de ses composés.
