The combination of atoms occurs because they want:

Correct answer: B. To attain an inert gas configuration

  • A. To decrease the number of electrons in the outermost shell
  • B. To attain an inert gas configuration
  • C. To increase the number of electrons in the outermost shell
  • D. To attain 18 electrons in the outermost shell

Explanation

Atoms form chemical bonds to achieve a more stable electron configuration, which is typically the configuration of the noble gases (like Neon or Argon). This "octet rule" is a major driving force for chemical bonding, as a full outer shell represents a state of low energy.

About Chemical Bonding

Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
