CAS 7439-92-1: Piombo
Descrizione:
Piombo, con il numero CAS 7439-92-1, è un metallo pesante classificato come metallo post-transizione. È noto per la sua malleabilità, duttilità e basso punto di fusione, che consente di essere facilmente modellato e formato. Piombo ha un colore bianco-azzurro quando viene tagliato fresco, ma si ossida a un grigio opaco quando esposto all'aria a causa della formazione di uno strato di ossido. È relativamente denso, con un alto peso atomico, e presenta una scarsa conducibilità elettrica rispetto ad altri metalli. Piombo è anche noto per la sua resistenza alla corrosione, rendendolo utile in varie applicazioni, tra cui batterie, schermature contro le radiazioni e materiali per saldatura. Tuttavia, Piombo è altamente tossico, in particolare per il sistema nervoso, e può causare gravi problemi di salute in caso di esposizione, portando a regolamenti rigorosi riguardo al suo uso e smaltimento. In termini di comportamento chimico, Piombo può formare vari composti, tra cui ossidi, solfuri e alogenuri, e di solito presenta uno stato di ossidazione +2 nella maggior parte dei suoi composti.
