CAS 7439-92-1: Lead

Description: Lead, with the CAS number 7439-92-1, is a heavy metal that is classified as a post-transition metal. It is known for its malleability, ductility, and low melting point, which allows it to be easily shaped and formed. Lead has a bluish-white color when freshly cut, but it tarnishes to a dull gray upon exposure to air due to the formation of an oxide layer. It is relatively dense, with a high atomic weight, and exhibits poor electrical conductivity compared to other metals. Lead is also known for its resistance to corrosion, making it useful in various applications, including batteries, radiation shielding, and soldering materials. However, lead is highly toxic, particularly to the nervous system, and can cause severe health issues upon exposure, leading to strict regulations regarding its use and disposal. In terms of chemical behavior, lead can form various compounds, including oxides, sulfides, and halides, and it typically exhibits a +2 oxidation state in most of its compounds.
