Nonmetals

In this post we are learning about metals and non metals and its characteristics.We find a list of metals explained in the periodic table.Nonmetals are elements group usually  considered to consist of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, and selenium.


Properties of Non metals:
 
Nonmetals have high ionization energies and electro negativities. They are generally poor conductors of heat and electricity. Solid nonmetals are generally brittle, with little or no metallic luster. Most nonmetals have the ability to gain electrons easily. Nonmetals display a wide range of chemical properties and reactivities.

 



List of the common properties which we find in a non metals.

  • High ionization energies
  • High electronegativities
  • Poor thermal conductors
  • Poor electrical conductors
  • Brittle solids
  • Little or no metallic luster
  • Gain electrons easily 
Some examples of non metals are brass, Aluminum, copper, etc. I hope this post was useful. Send in your comments and suggestions .
