CAS 7439-92-1
:Blei
Beschreibung:
Blei, mit der CAS-Nummer 7439-92-1, ist ein Schwermetall, das als Post-Übergangsmetall klassifiziert wird. Es ist bekannt für seine Verformbarkeit, Duktilität und niedrige Schmelztemperatur, die es ermöglichen, es leicht zu formen und zu gestalten. Blei hat eine bläulich-weiße Farbe, wenn es frisch geschnitten ist, aber es läuft beim Kontakt mit Luft zu einem stumpfen Grau an, was auf die Bildung einer Oxidschicht zurückzuführen ist. Es ist relativ dicht, hat ein hohes Atomgewicht und zeigt im Vergleich zu anderen Metallen eine schlechte elektrische Leitfähigkeit. Blei ist auch bekannt für seine Korrosionsbeständigkeit, was es in verschiedenen Anwendungen nützlich macht, einschließlich Batterien, Strahlenschutz und Lötmaterialien. Allerdings ist Blei hochgiftig, insbesondere für das Nervensystem, und kann bei Exposition zu schweren Gesundheitsproblemen führen, was zu strengen Vorschriften bezüglich seiner Verwendung und Entsorgung führt. In Bezug auf das chemische Verhalten kann Blei verschiedene Verbindungen bilden, einschließlich Oxiden, Sulfiden und Halogeniden, und zeigt typischerweise einen Oxidationszustand von +2 in den meisten seiner Verbindungen.
