Chemical Bonds

Attractive forces that allow atoms to join together to form molecules.

Ionic Attraction

The attraction between positively and negatively charged ions.

Covalent Bond

A bond formed by the sharing of electron pairs between atoms.

Study Notes

Electron Shells and Energy

  • Atoms have electron shells with a maximum number of electrons each can hold
  • Inner shells fill before outer shells
  • Atoms with incomplete outer shells are more likely to react

Atoms Interact and Form Molecules

  • Chemical bonds link atoms in molecules
  • Ionic bonds form when atoms gain or lose electrons
  • Covalent bonds form when atoms share electrons
  • Hydrogen bonds form due to attraction of a hydrogen atom to another electronegative atom

Chemical Bonds and Interactions

  • Ionic bonds are formed by attractions between oppositely charged ions
  • Covalent bonds are formed by sharing pairs of electrons
  • Hydrogen bonds are attractions between a hydrogen atom (partially positive) and another atom with a high electronegativity (partially negative).
  • Hydrophobic interactions occur in the presence of polar substances between nonpolar substances
  • van der Waals forces are weak attractions between molecules
