Copper

Description:
Copper, with the CAS number 7440-50-8, is a transition metal known for its distinctive reddish-brown color and high thermal and electrical conductivity. It is malleable and ductile, allowing it to be easily shaped into wires and sheets. Copper has a relatively high melting point and boiling point compared to many other metals, which contributes to its stability in various applications. It is resistant to corrosion, particularly in dry environments, but can tarnish when exposed to moisture and air, forming a green patina over time. Copper is an essential trace element in biological systems, playing a crucial role in various enzymatic processes. In terms of reactivity, it can form compounds with nonmetals and is often found in oxidation states of +1 and +2. Copper is widely used in electrical wiring, plumbing, and as an alloying agent in bronze and brass, making it a vital material in both industrial and everyday applications. Its unique properties make it a key component in many technological advancements.
