Class 11 Chemistry Chemical Bonding Structure COVALENT BOND

COVALENT BOND

They are formed by mutual sharing of electrons between combining atoms

Like in:

  • Hydrogen chloride molecule

Class_11_Chemistry_Chemical_Bonding_HCl

 

  •  Oxygen molecule

 Class_11_Chemistry_Chemical_Bonding_OxygenMolecule

  •  In Nitrogen molecule

Terms to know:

  • Valence electrons: The electrons present in valence shell.
  • Lone pair: The electrons that do not participate in bond formation.
  • Bond pair: The electrons that participate in bond formation.
