List 3 unique properties of molecular compounds. 9. A covalent bond involves a chemical bond between 2 atoms that are electrons. When atoms share electrons, each achieves a complete most atoms). Typically, covalent bonds involve what type(s) of elements? (for 10. What is the definition of a single, double, and triple bond? 11. Provide an example of a compound for each type of bond in the previous question. 12. All diatomic elements form bonds. Diatomic elements include, and (ionic/polar covalent/nonpolar covalent).l '.l l 13. structures depict the bonding in a molecule. The first step in drawing these structures is determining the number of in the molecule.

7 14. When it is possible to write 2 or more valid Lewis structures for a molecule or ion, it is called An example of a molecule or ion that shows this is Draw the resonance forms below: 15. Draw the Lewis structure for: water, sulfur dioxide, carbon tetraiodide, carbon monoxide, nitrite ion, carbon dioxide, ammonia, ethene (C2H4) and phosphate ion. 16. The theory states that because electron pairs shapes adjust so the valence electron pairs are as far apart as possible.., molecular 17. Determine the geometry or shape of each molecule or ion in #15. For ethene, determine the geometry around each carbon atom. 18. The degree of polarity of a bond between any two atoms can be determined by determining the difference in 19. A bond is considered nonpolar covalent if the electronegativity difference between the two atoms is.; polar covalent if the electronegativity difference is and ionic if the electronegativity difference is 20. Ionic, nonpolar covalent, or polar covalent bond? a) H-P b) H-O c) Li-F d) C-I e) P-CI 21.
