What is Copper?

  • For thousands of years, Copper is a metal that has been a part of our civilization. Silver, gold, copper, and Iron all have been made use in one way or another.
  • Copper(Cu) is one of those elements that were never actually discovered. They have been a part of each footstep in the growth of civilization. We keep on learning the diverse places where copper is made use of in nature.
  • The metal has been used for such an extended time as it can be found secluded as an unadulterated element. One could be tunnelling in a mine and stumble across unadulterated copper in various forms.
  • It is the 29th element in the periodic table represented by the symbol ‘Cu‘ short for the Latin name ‘cuprum’.

Uses Of Copper

  • Copper sulphate is used widely as an agricultural poison and as an algicide in water purification.
  • While one may not consider copper being used for something other than coins, it is a crucial element in the creation of bronze.
  • Historically, copper was the first metal to be worked by people. The discovery that it could be hardened with a little tin to form the alloy bronze gave the name to the Bronze Age.

Certain Facts About Copper

  • Copper is an essential element. An adult human needs around 1.2 milligrams of copper a day, to help enzymes transfer energy in cells. Excess copper is toxic.
