Read each question carefully and provide your best answer. For multiple choice questions, circle the correct option. For fill-in-the-blanks, complete the sentence with the appropriate term. For short answer questions, write your response on the lines provided.
Covalent bonds are formed when atoms share electrons to achieve a stable electron configuration, typically an octet. This type of bonding usually occurs between two nonmetal atoms.
1. Which of the following best describes a covalent bond?
Transfer of electrons between atoms.
Sharing of electrons between atoms.
Attraction between oppositely charged ions.
Formation of a metallic lattice.
2. Covalent bonds typically form between which types of elements?
Metal and nonmetal.
Metal and metal.
Nonmetal and nonmetal.
Noble gas and nonmetal.
3. In a covalent bond, atoms electrons to achieve a stable outer shell.
4. A single covalent bond consists of shared electrons.
5. Water (H2O) is an example of a molecule formed by bonds.
6. Covalent compounds generally have high melting and boiling points.
True
False
7. Only two atoms can be involved in a single covalent bond.
True
False
8. Explain the difference between polar and nonpolar covalent bonds.
9. Give two examples of common molecules that exhibit covalent bonding and briefly describe their structure (e.g., single, double, or triple bonds).
