What is coper?

Copper is a chemical element with the symbol Cu and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. Copper is known for its reddish-brown color and its ability to form patina over time, which is a greenish layer that results from oxidation.

Copper has been used by humans for thousands of years, dating back to the ancient civilizations of Egypt, Greece, and India. It is an essential nutrient for all living organisms and is commonly found in foods such as liver, shellfish, and grains.

In addition to its biological and cultural significance, copper has numerous industrial and technological applications. It is widely used in construction, electrical wiring, and plumbing due to its excellent conductivity and durability. Copper is also used in the manufacture of coins, jewelry, and decorative objects.

Despite its usefulness, copper can be toxic in high concentrations. Exposure to copper dust or fumes can cause skin irritation, lung problems, and other health issues. However, copper is generally considered to be safe when used appropriately and in low concentrations.
