    What determines the type of chemical bond?

    Electronegativities of the bonded atoms.

    What characterizes an ionic bond?

    Large difference in electronegativity.

    How does a metallic bond differ from ionic and covalent bonds?

    Both sum and difference in electronegativity are small.

    What happens to the size of anions during formation?

    An increase in size occurs.

    What is the consequence of forming cations?

    A decrease in size occurs.

    What energy is required to form cations?

    Ionization energy is needed.

    What is the role of electron affinity in an ionic bond?

    It releases energy during anion formation.

    What is a characteristic of the energy levels in metallic bonds?

    They form closely spaced orbitals.

    What occurs during the formation of covalent bonds?

    Molecules are formed from free atoms.

    What is colligation in covalent bonding?

    Each atom contributes one electron to the bond.

    What defines bond length?

    The distance between the nuclei of bonded atoms.

    How is bond energy related to bond length?

    Shorter bonds generally have greater bond energy.
