Copper



Copper is an element that is thought to be formed scattered by the nuclear fusion reactions that occur in an exploding star called supernova. Some of the copper was found in what is now northern Iraq. Copper can be found in many minerals like cuprite, malachite, azurite, chacopyrite, and bomite. It is believed that copper was found by humans 10,000 years ago.

Copper was known since ancient times by many civilizations. The earliest evidence of copper was found around 10,000years ago. In 10,000BCE in North America when copper was developed many people believed that copper began in South America when heat was used to melt copper before 1,000BCE. In 5,000BCE people in the same place began to use heat to melt copper. Before 3,500BCE bronze and copper and tin was called as the “Bronze age” in Europe and Asia. Copper was used to write and record many great details in to the tomb paintings of ancient Egypt. By the time when the Europeans invaded in the 16th century the Incas of Peru developed bronze and copper.

Some uses of copper these days are electrical cables, all American coins, gunmetal and decorations. Copper is a very great element for electrical cables because it is strong and it can last a very long time. Since copper is very strong and it is guaranteed to last a long time the Statue of Liberty is made out of copper. Copper is 98% to 99.5% pure. This is why it is used for products of great quality.

Copper has an atomic number of 63. This means that this is the number of protons and electrons in each atom. Copper also has an atomic mass of 29, the atomic mass is how many protons and neutrons it has all together in the nucleus. Electrons are a part of the atom that has a negative electrical charge. There are 29 protons, 34 neutrons and 29 electrons in copper. Protons are a part of the atom that has a positive charge. Neutrons are a part of an atom that has neither a positive nor negative charge. Both protons and neutrons are in the nucleus.

Copper is an element that is not a very reactive element. Conductivity spreads out electrons. It expands as the amount of heat that follows per unit distance. Copper can be folded, it can also be able to be pressed for a along time with out breaking or cracking. Copper has a pinkish or peachy color.
