What is molecule and it’s types?

Molecule definition types and Examples :

Molecule definition types and examples  is listed here briefly by the way you can clear your doubts about molecules and their types.First we discussed what is molecule.

What is a molecule? 

Molecule is a substance formed by combination of two or more atoms.e.g

Molecule definition types and importance
A molecule of CO2

Types of molecules

  • Monoatomic molecules
  • Diatomic molecules
  • Triatomic molecules
  • Polyatomic molecules
  • Homoatomic molecules
  • Hetroatomic molecules

    Monoatomic moleculesMONOATOMIC

  • The molecules which consists of only one atom are called Monoatomic molecules. e. g Hydrogen, Nitrogen
  • Diatomic moleculesDiatomic Molecule

  • The molecules which consists of two atoms are known as diatomic molecules. e. g H2 ,O2
  • Triatomic moleculesco2

  • The molecules which consists of three atoms are known as triatomic molecules. e. g H2S, CO2
  • Polyatomic molecules.HNO3

    Molecule definition types and importance
    HNO3 molecule
  • The molecules which consists of many atoms are known as Polyatomic molecules. e. g H2SO4,HNO3
  • Homoatomic molecules:C6H6

    Molecule definition types and importance
    C6H6 Homoatomic molecule
  • The molecules which consists of same type of atoms are known as Homoatomic molecules. e. g S8,C6H6
  • Hetroatomic molecules:H2SO4

    Molecule definition types and importance
    H2SO4
  • The molecules which consists of different types of atoms are known as Hetroatomic molecules. e.g H2SO4,HNO3.
  • Importance of molecules

  • Molecules are very important for us
  • For example water is a molecule made up of two atoms of hydrogen and one atom of oxygen. Life is not possible without water. Our 70% body mass is made up of water.It has equal importance for both plants and animals.
  • Similarly DNA molecule is the part of every living cell.It is double stranded molecule having double heluxe shape. The two strands are wrapped around each other.It is made up of sugar phosphate and nitrogen bases. It is the permanent storage place for genetic information. This genetic information is transferred from one generation to next generation.DNA synthesize RNA which is responsible for genetic information in work. RNA receive information, reads it, decode it and according to the instructions make the new proteins.If there is any disorder takes place in it faulty protein is formed and the protein do not work properly.Due to this genetic diseases occure. So DNA is very important molecule. It plays a very important role in our genes.
