πŸ“š Quick Study Guide

  • βš›οΈ A molecule is a group of two or more atoms held together by chemical bonds.
  • 🀝 Covalent bonds involve the sharing of electrons between atoms.
  • βž• Ionic bonds involve the transfer of electrons between atoms, creating ions.
  • πŸ’§ Polar molecules have an uneven distribution of electron density, leading to partial charges.
  • 🌐 Nonpolar molecules have an even distribution of electron density.
  • βš–οΈ Molecular weight is the sum of the atomic weights of all atoms in a molecule.
  • 🌑️ Intermolecular forces (e.g., hydrogen bonding, van der Waals forces) affect a substance's physical properties like boiling point.
