b.Metallic bond
c.Ionic Bond

Answer 1

Here are the matches between Column A and Column B based on the descriptions provided:

1. **A bond in which electrons are shared between two atoms.** - **a. Covalent Bond**
2. **A bond between two nonmetals.** - **a. Covalent Bond**
3. **A bond between a metal and a nonmetal.** - **c. Ionic Bond**
4. **The bond between Calcium and oxygen in calcium oxide.** - **c. Ionic Bond**
5. **The bond between carbon and oxygen in carbon monoxide.** - **a. Covalent Bond**
6. **A type of bond formed between positively charged metal atoms in which free electrons are shared.** - **b. Metallic bond**

So the final matching looks like this:

- 5. → a. Covalent Bond
- 6. → a. Covalent Bond
- 7. → c. Ionic Bond
- 8. → c. Ionic Bond
- 9. → a. Covalent Bond
- 10. → b. Metallic bond
