Matching the type of bond to its description:
1. Covalent - a bond between a metal and a nonmetal
2. Ionic - electrons are transferred
3. Covalent - electrons are shared
4. Covalent - a bond between two nonmetals
5. Ionic - NaCI
6. Covalent - CO2
7. Ionic - highly conductive when dissolved in water
8. Covalent - not conducive or not very conductive when dissolved in water
To match the type of bond to its description, let's go through each description and determine which bond type it corresponds to:
1. A bond between a metal and a nonmetal: This is typically an ionic bond since metals tend to lose electrons and nonmetals tend to gain electrons to achieve a stable electron configuration. Therefore, the answer is B. ionic.
2. Electrons are transferred: Once again, the transfer of electrons corresponds to an ionic bond. The answer is B. ionic.
3. Electrons are shared: In this case, electrons are shared between atoms, indicating a covalent bond. Therefore, the answer is A. covalent.
4. A bond between two nonmetals: This scenario also corresponds to a covalent bond since nonmetals typically share electrons. Hence, the answer is A. covalent.
5. NaCl: Sodium chloride (NaCl) is an ionic compound, as it is formed through the transfer of electrons between sodium (metal) and chlorine (nonmetal). Therefore, the answer is B. ionic.
6. CO2: Carbon dioxide (CO2) consists of two nonmetals, carbon, and oxygen, which form covalent bonds by sharing electrons. Hence, the answer is A. covalent.
7. Highly conductive when dissolved in water: Ionic compounds tend to dissociate into ions when dissolved in water, allowing them to conduct electricity. Therefore, the answer is B. ionic.
8. Not conducive or not very conductive when dissolved in water: Covalent compounds do not dissociate into ions in water and generally do not conduct electricity well. Hence, the answer is A. covalent.
