What to Focus On

  • Chemical bond formation lowers the energy of the system.
  • Atoms bond to achieve stable electron configurations like noble gases.
  • Bonds form by electron transfer (ionic) or electron sharing (covalent).

  • Electron transfer leads to ion formation.
  • Electrostatic attraction between cations and anions forms the bond.
  • Ionic compounds are crystalline, have high melting points, and conduct electricity in molten or aqueous state.

  • Electron sharing forms covalent bonds.
  • Bond strength depends on the extent of orbital overlap.
  • Polar covalent bonds have unequal electron sharing due to electronegativity difference.

Common Mistakes to Avoid

All chemical bonds involve transfer of electrons.

Covalent compounds cannot conduct electricity under any condition.

Double bonds are just two single bonds side by side with same strength and properties.

Memory Tips

Octet Rule: Atoms tend to have 8 electrons in their valence shell for stability.

Ionic bond formation via electron transfer (e.g., NaCl)

Covalent bond: sharing of electrons between atoms

Polar covalent bond: unequal sharing due to electronegativity difference
