  • Overlap of atomic orbitals (correct)
  • Sharing of ionic charges
  • The concept of hybridization in valence bond theory is used to explain:

  • The arrangement of electrons in atoms
  • The formation of ionic bonds
  • The shapes of molecules (correct)
  • The transfer of electrons between atoms
  • According to valence bond theory, the term 'resonance' is used to describe:

  • The transfer of electrons between atoms
