CAS 7440-23-5
:Natrium
Beschreibung:
Natrium, mit der CAS-Nummer 7440-23-5, ist ein hochreaktives Alkalimetall, das zur Gruppe 1 des Periodensystems gehört. Es zeichnet sich durch sein weiches, silberweißes Aussehen aus und ist bekannt für seine geringe Dichte, die geringer ist als die von Wasser. Natrium hat einen Schmelzpunkt von etwa 98 Grad Celsius und einen Siedepunkt von etwa 883 Grad Celsius. Es verliert leicht ein Elektron, um ein Kation (Na+) zu bilden, was es hochreaktiv macht, insbesondere mit Wasser, wobei Natrium-Hydroxid und Wasserstoffgas entstehen. Diese Reaktivität erfordert, dass Natrium unter Öl oder in einer inert Atmosphäre gelagert wird, um zu verhindern, dass es mit der Feuchtigkeit in der Luft reagiert. Natrium spielt eine entscheidende Rolle in biologischen Systemen, insbesondere bei der Nervenfunktion und dem Flüssigkeitsgleichgewicht. Es ist auch ein wesentlicher Bestandteil in verschiedenen industriellen Anwendungen, einschließlich der Glasproduktion, Seifen und als Wärmetauscher in Kernreaktoren. Aufgrund seiner Reaktivität muss Natrium mit Vorsicht behandelt werden, und es sollten geeignete Sicherheitsmaßnahmen getroffen werden, wenn mit diesem Element gearbeitet wird.
