CAS 7440-57-5
:Gold
Description:
Gold, with the Chemical Abstracts Service (CAS) number 7440-57-5, is a highly valued metallic element known for its distinct yellow color and luster. It is classified as a transition metal and is represented by the symbol Au on the periodic table. Gold is characterized by its excellent malleability and ductility, allowing it to be easily shaped into thin sheets or drawn into wires without breaking. It is also highly resistant to corrosion and oxidation, making it stable in various environments. Gold has a high density and is a good conductor of electricity and heat. Chemically, it is relatively inert, reacting only with a few substances, such as halogens and cyanides, under specific conditions. Gold is often found in nature in its native form, typically in alluvial deposits, and is commonly used in jewelry, electronics, and as a standard for monetary systems due to its intrinsic value and rarity. Its unique properties and aesthetic appeal have made it a symbol of wealth and prestige throughout history.
