1. It is an electrical attraction between the nuclei and valence electrons of an atom and which bind atoms together. 2. A type of bond which results from the transfer of one or more valence electrons from one atomt another. 3. It is a bond in which the electrons are equally shared by bonded atoms. 4. It is a bond in which the bonded atoms have an unequal sharing of electrons. S. It is a measure of the tendency of an atom to attract electrons toward itself. 6. These are forces of attraction that exist between the molecules that comprise matter. 7. These are intermolecular forces of attraction acting on polar molecules. 8 It is a cpecial type of dinole-dipale interaction when a hydrogen atom bonded ta a highly electronegative atom is attracted to an unshared pair of electrons of an electronegative atom of another molecule. 9. These forces result from the constant movement of electrons in molecules, whích consequently creates instantaneous dipoles. I1. Write T if the answer is true and F if the answer is false. 10. The strength of a substance's intermolecular attractive force determines many of its physical properties. 11. Substances with higher boiling points possess stronger intermolecular forces of attraction. 12. A polar substance is only soluble in another polar substance. 13. London dispersion forces are the weakest type of intermolecular force of attraction. 14. The polarity of covalent bonds in a molecule helps determine the polarity of the whole molecule 15. The molecular geometry affects the polarity of the whole molecule. 16. If sharing of an electron pair between atoms exists, an ionic bond is said to be formed. Based on the metallic properties of elements, predict first if the bond between the pair of aton ionic or covalent. Then, calculate the electronegativity difference between the atoms to furthe classify the bonds as polar or nonpolar. (Write your solution in the table below) Determine the more electronegative atom in each pair. (9 points) III.
