  title: Chemical Bond Types
  description: Primary types of chemical bonds and interactions.
  summary: "The principal types of chemical bonding and interaction: ionic, covalent, metallic, hydrogen and van der Waals bonds, with polar and nonpolar covalent bonds, coordinate bonds, dipole-dipole, London dispersion and ion-dipole forces, each with an example."
  use_when:
    - You need to classify a bond or explain why a substance has a certain melting point or solubility.
    - You are comparing strong (intramolecular) and weak (intermolecular) interactions.
  caveats:
    - Bond types are idealizations; most bonds have mixed ionic and covalent character.
    - Hydrogen bonds and van der Waals forces are attractions between molecules, much weaker than covalent or ionic bonds.

data:
  - bond: Ionic
    description: Electrostatic attraction between oppositely charged ions.
    example: NaCl
  - bond: Covalent
    description: Atoms share electron pairs.
    example: H2O
  - bond: Metallic
    description: Electrons are delocalized among metal cations.
    example: Cu, Fe
  - bond: Hydrogen
    description: Attraction between a hydrogen atom and an electronegative atom.
    example: H2O hydrogen bonds
  - bond: Van der Waals
    description: Weak intermolecular forces from transient dipoles.
    example: Noble gas liquids
  - bond: Polar Covalent
    description: Electrons are shared unequally because the atoms differ in electronegativity, giving partial charges.
    example: HCl
  - bond: Nonpolar Covalent
    description: Electrons are shared equally or nearly equally between atoms of similar electronegativity.
    example: H2, N2
  - bond: Coordinate (Dative) Covalent
    description: Both bonding electrons come from one atom.
    example: NH4+ formed from NH3 and H+
  - bond: Dipole-Dipole
    description: Attraction between the partial positive end of one polar molecule and the partial negative end of another.
    example: Acetone molecules
  - bond: London Dispersion
    description: Weak attraction from temporary fluctuations in electron distribution; present in all molecules.
    example: Noble gases, methane
  - bond: Ion-Dipole
    description: Attraction between an ion and a polar molecule, important in dissolving salts.
    example: Na+ surrounded by water molecules
