Chemical bonds are forces that hold atoms together to make compounds or molecules.Chemical bonds are the connections between atoms in a molecule. These bonds include both strong intramolecular interactions, such as covalent and ionic bonds. They are related to weaker intermolecular forces, such as dipole-dipole interactions, the London dispersion forces, and hydrogen bonding. The weaker forces will be discussed in a later concept.

  • Chemical bonds include covalent, polar covalent, and ionic bonds.
  • Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds.
  • Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other. This attraction is known as an ionic bond.
  • ionic bond: An attraction between two ions used to create an ionic compound. This attraction usually forms between a metal and a non-metal.
  • covalent bond: An interaction between two atoms, which involves the sharing of one or more electrons to help each atom satisfy the octet rule. This interaction typically forms between two non-metals.
  • intramolecular: Refers to interactions within a molecule.
  • intermolecular forces: Refers to interactions between two or more molecules
