Copper element in Periodic table
The Copper element (Cu) has the atomic number 29 and is located in group 11 and period 4. Copper is a metal and it is classified as a transition element.
Facts about copper
Here are a few interesting facts about copper element.
- Copper was given its name from the Latin word “cuprum”.
- The earth’s crust has the copper in the concentration of 50 ppm.
- Igneous rocks contain a lot of copper and around 2/3rd of the copper is obtained from the igneous rocks.
- Most of the copper is used in manufacturing of electrical wires and other electrical transmission systems.
- Copper is the 3rd most used metal in the industries. (The first is iron and second is aluminum).
- Copper ranks 2nd in terms of electrical conductivity as well as thermal conductivity. (The 1st is silver which has the best thermal and electrical conductivity).
- Copper is the only metal that is in reddish-orange color.
- Copper is easily recyclable and it can be used again and again.
Properties of copper
Here is a list of some physical properties and chemical properties of copper.
Physical properties of copper
- Copper is a metal having a reddish-orange lustrous appearance.
- Copper is a good conductor of heat as well as electricity.
- Copper is highly ductile metal and it can easily be drawn into thin wire.
- The copper has an atomic mass 63.546 u and its density is 8.96 g/cm3.
- 63Cu is the most abundant naturally occurring isotope of copper. It has an abundance of around 69%.
- The melting point and boiling point of copper is 1357.7 K and 2835 K respectively.
Chemical properties of copper
- Copper has an electron configuration: [Ar] 3d10 4s1; and the electronic configuration of its most common oxidation state Cu2+ is: [Ar] 3d9 4s0. This indicates that the copper is a transition element.
- Copper present in the sample gives a greenish color in the flame test.
- Copper reacts slowly with the oxygen of the air and this forms a greenish layer on the copper.
Uses of copper
Here are some uses of the copper element.
- Copper is used as an alloying metal with other metals to get the improved properties. Bronze and brass are the most common alloys of copper.
- The ship hulls are also made up of brass, which prevents the growth of algae on it.
- Copper is also used in cookwares, coin manufacturing as well as in plumbing pipes.
- Copper is present in almost all the electronics devices like radio, TV, mobile phones, laptops, etc.
- Copper is a natural antibacterial agent. Because of this reason the brass (which is an alloy of copper) is used in door handles of public buildings. This helps in preventing disease transmission.
- Copper is also used in earthing of buildings to protect the building from lightning.
