👉 Organoantimony is a type of heavy metal that has been used in various applications due to its unique properties. It consists of one or more isotopes of antimony, which are known as lanthanides. The lanthanide elements contain 19 isotopes, and the compound undergoes radioactive decay with different half-lives depending on the number of isotopes present. Organoantimony is typically found in ores such as chalcopyrite (a common ore of antimony)
