  • Copper is a chemical element with atomic number 29 and symbol Cu. The Density of copper is 8.96. The atomic number of coppers is 29.
  • 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 is one of those elements that were never actually discovered. They have been a part of each footstep in the growth of civilization.
  • The metal has been used for such an extended time as it can be found secluded as an unadulterated element. One could be tunneling in a mine and stumble across unadulterated copper in various forms.
  • It is the 29th element in the periodic table represented by the symbol short for the Latin name ‘cuprum’ .

Density of Copper

The Density of copper is g/

  • Density of a pure solid chemical element is always listed as the density of the equilibrium crystalline state of that element, usually at room temperature unless specified otherwise.
  • This information must be borne in mind when considering the density for example, of copper which has an FCC crystal structure.
  • The packing fraction for an FCC close packed structure of hard spheres is 0.740.
  • The slight discrepancy between the two methods of calculated adding fractions is due to truncation and rounding off.
  • The density of copper in the amphorous solid state at room temperature can be predicted by the ratio of packing fraction. Copper is the most naturally occurring element other than gold with a distinctive hue. Unlike gold and silver, copper is a magnificent conductor of heat and electricity. It՚s very malleable and ductile, too. Copper is also corrosion-resistant (it does not rust very easily) .

Important Uses of Copper

  • Copper sulfate 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.
  • It is used for a whole range of goods, from cans, cooking foil and saucepans through to electricity cables, planes, and space vehicles.
  • Electrical conductivity is especially important because wire accounts for more than 50 % of copper consumption worldwide.
  • Chemical vapor deposition, which is used in semiconductor manufacture, involves the deposition of thin copper films from a gas- phase precursor.
  • Copper is used largely as an alloy of gold and silver, and it is often plated with one or the other.

Certain Facts About Copper

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


Why is Copper Ideal for Making Wires?


Some desirable properties of copper that make it ideal for electrical wiring applications are:

  • Copper, like most other metals, has very high electrical conductivity.
  • The tensile strength exhibited by copper is also very good.
  • Copper is a highly ductile metal, implying that it can easily be drawn into wires.
  • Copper shows excellent resistance to deformation and creep.
  • This metal is also highly resistant to corrosion.
  • Copper also has very high thermal conductivity. This property, in combination with its low thermal expansion, makes it highly useful for wiring applications.
  • The malleability of copper is another reason why it is preferred for the production of wires.
  • Copper can also be easily soldered.

These properties of copper make it the ideal choice of metal for the production of electrical wires.

What Are the Melting and Boiling Points of Copper?


The melting point of copper is equal to , or The boiling point of copper is approximately equal to , or . Thus, it can be understood that copper (like most other metals) has a very high melting point and also a very high boiling point.

Why is Copper Denoted by the Symbol ‘Cu’ ?


The symbol ‘Cu’ denotes the Latin name of copper, which is Cuprum. Copper can be classified as a native metal which can occur in nature in its pure form.

Why is Copper So Important?


Copper is a resource and an important part of our daily lives. This is a major industrial metal due to its high ductility, malleability, thermal and electrical conductivity and corrosion resistance.

What Are the Uses and Properties of Copper?


Most copper is used in electrical equipment such as wiring and motors. This is because it conducts both heat and electricity very well, and can be drawn into wires. It also has uses in construction, and industrial machinery.

What Are Properties of Copper?


  • It is malleable, ductile, and an extremely good conductor of both heat and electricity. It is softer than zinc and can be polished to a bright finish.
  • It is found in group of the periodic table, together with silver and gold. Copper has low chemical reactivity.
