Chemical Bond

A chemical bond is defined as the force of attraction between any two atoms in a molecule to maintain stability.

      Reasons for Chemical Bonding

  • The driving force for atoms to combine is related to the tendency of each atom to attain stable electronic configuration of the nearest inert noble gas.
  • For an atom to achieve stable electronic configuration, it must have
  • Two electrons in the outermost shell (nearest noble gas He) – Duplet rule
  • Eight electrons in the outermost shell (all noble gases other than He) – Octet rule

Ionic bond
