Copper

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. It is commonly used in electrical wiring, plumbing, and for making alloys such as brass and bronze.

Physical Properties of Copper:

• Atomic Number: 29
• Symbol: Cu
• Melting Point: 1,984°F (1,085°C)
• Boiling Point: 5,301°F (2,927°C)
• Color: Reddish-orange

Chemical Properties of Copper:

• Copper does not react with water, but it slowly reacts with atmospheric oxygen to form a layer of brown-black copper oxide.
• It reacts with acids and can be dissolved in hot concentrated sulfuric or nitric acid.

Uses of Copper:

Copper is widely used in various applications, including:

• Electrical wiring and conductors
• Plumbing and piping
• Cookware and kitchen utensils
• Construction materials
• Coins and jewelry

Environmental Impact:

Copper is a naturally occurring element and is essential for many living organisms. However, excessive copper exposure can be toxic to aquatic life and can impact human health if ingested in large amounts.
