History of copper

Copper was the first metal manipulated by humans, and it remains an important metal in industry today (Pappas, 2018). It can be found naturally in pure metallic form; therefore, it was relatively easy for ancient humans with their primitive tools to extract and use copper without the need for complicated techniques and technology that was developed later by the mankind.

As a chemical element, copper has the following properties:

  • Atomic number (number of protons in the nucleus): 29
  • Atomic symbol (on the periodic table of elements): Cu
  • Atomic weight (average mass of the atom): 63.55
  • Density: 8.92 grams per cubic centimetre
  • Phase at room temperature: solid
  • Melting point: 1,984.32 degrees Fahrenheit (1,084.62 degrees Celsius)
  • Boiling point: 5,301 degrees F (2,927 degrees C)
  • Number of isotopes (atoms of the same element with a different number of neutrons): 35; 2 stable
  • Most common isotopes: Cu-63 (69.15 percent natural abundance) and Cu-65 (30.85 percent natural abundance)
