Chemical Bond: An attractive force that holds atoms, ions, or molecules together in a chemical species, resulting from interactions between electrons and nuclei.
Covalent Bond: A type of chemical bond formed by the mutual sharing of electron pairs between two atoms, typically nonmetals.
Ionic (Electrovalent) Bond: A bond formed by the transfer of electrons from a metal to a non-metal, resulting in oppositely charged ions held together by electrostatic forces.
Coordinate (Dative) Bond: A special covalent bond where both shared electrons originate from one atom, often seen in complex ions and molecules.
Bond Polarity: The distribution of electrical charge across a bond, resulting in partial positive and negative charges; depends on differences in electronegativities of bonded atoms.
Bond Length: The equilibrium distance between the nuclei of two bonded atoms; shorter bonds generally indicate stronger bonds.
