  1. Copper Jordan Wells

  2. Basic Information • Symbol: CU • Atomic Number: 29 • Atomic Mass:63.546 amu • Group on the periodic table: Coinage Metal

  3. History • Copper was the first metal mined and crafted by man. Evidence states that copper was used and discovered more than 10,000 years ago in Western Asia. The discover was unknown. • The name came from Latin word cyprium, after the island Cyprus • The symbol comes from the Latin word cuprum which is shortened to Cu.

  4. Compounds where it commonly exists • Many compounds of copper exist, and some occur naturally while others are man-made. • The most common one is copper sulfate. It’s common name is copper sulfate, but is also known as Blue Vitrol, Bluestone and Cupric Sulfate, formula: CuSO 4 • Malachite- formula: Cu2, CO3(OH)2, common name: Malachite

  5. Where copper’s most useful • Copper is used mostly in electronics and money.

  6. Appearance in natural form • Pure copper is soft and malleable which means it can be bent and shaped without having its form messed up, and it has a reddish orange color.

  7. Physical properties • Melting point: 1083.0 °Celsius, 1981.4 °Fahrenheit • Boiling point: 2567.0 °Celsius, 4652.6 °Fahrenheit • Density: 293 Kelvin, 8.96 g/cm3 • Some properties are it’s an excellent electrical conductor, non magnetic, recyclable, durable, machinable and etc.

  8. State of matter it exists at room temperature • Copper’s state of matter at room temperature is a solid

  9. Chemical Properties • Copper has a low chemical reactivity. • It’s a reasonably active. It dissolves in most alkalis which are chemicals that have properties the opposite of acids. • It reacts well with oxygen. In humid air, it combines with water and carbon dioxide.

  10. Extra Information-The use of Copper in ancient times • A few random facts: One of the famous Dead Sea Scrolls found in Israel is made of copper instead of fragile animal skins. The scroll contains clues to a still undiscovered treasure. When Columbus sailed to America, his ships (Nina, Pinta, and Santa Maria) had copper skins below the water line. The copper covering extended hull life and protected the ships against barnacles and other types of biofouling. Today, most sea-going vessels use a copper-based paint for protection. • Israel’s Timna Valley provided copper for the Pharaohs. Records stated that copper form Ancient Egypt was used to treat infections and clean water. The island of Cyprus(where it’s got its name) have supplied much needed copper for empires of the ancient Phoenicia, Greece, and Rome.

  11. Extra information- Copper Sulfate • Copper sulfate is a chemical compound which is produced commercially by reacting various coppers with sulfuric acid. • Copper should be handled exceptionally well, because it is toxic and acidic and can cause health risks to (living) organisms. • It appears in a crystal form and varies from bright blue to green. Copper sulfate dissolves very easily. • Copper sulfate is used to create beautiful blue fireworks. • It’s also used in agriculture as a treatment for crops and water systems. • It has also been used(decades ago) to dye textiles.
