Read each question carefully and provide your answer in the space provided. For multiple-choice questions, circle the letter corresponding to the correct answer. For true/false, circle T or F. For short answers, explain your reasoning.
1. Which type of bond involves the complete transfer of electrons between atoms?
Covalent bond
Ionic bond
Metallic bond
Hydrogen bond
2. What is the primary force holding atoms together in a metallic bond?
Electrostatic attraction between ions
Sharing of electron pairs
Attraction between positive metal ions and a 'sea' of delocalized electrons
Intermolecular forces
3. A bond typically forms between a metal and a nonmetal.
4. In a covalent bond, electrons are between atoms.
5. The ability of metals to conduct electricity is due to the presence of electrons.
6. Describe the difference in electron behavior between an ionic bond and a covalent bond.
7. Explain why ionic compounds typically have higher melting points than covalent compounds.
8. All compounds formed between two nonmetals are covalent.
True
False
9. Metallic bonds are characterized by strong, directional bonds between individual atoms.
True
False
10. Observe the image below depicting covalent bond formation.
Based on the illustration, describe how the atoms achieve a stable electron configuration.
11. Observe the image below depicting ionic bond formation.
Based on the illustration, identify the cation and anion formed in this bond.
