### Ionic Bonds Quiz **Question:** Which of the following contains an ionic bond? - ○ NaCl - ○ SO₂ - ○ Cu-Zn Alloy - ○ CO₂ **Explanation:** To answer this question, it is essential to understand what an ionic bond is. An ionic bond is a type of chemical bond that involves the electrostatic attraction between oppositely charged ions. Ionic bonds typically occur between a metal and a non-metal. **Correct Answer:** - **NaCl** - Sodium Chloride (NaCl) is a classic example of an ionic compound. It consists of sodium ions (Na⁺) and chloride ions (Cl⁻), which are held together by strong electrostatic forces of attraction. **Other Options:** - **SO₂** (Sulfur Dioxide) - Contains covalent bonds between sulfur and oxygen atoms. - **Cu-Zn Alloy** (Brass) - An alloy is a mixture of metals and does not form ionic bonds; it has metallic bonds. - **CO₂** (Carbon Dioxide) - Consists of covalent bonds between carbon and oxygen atoms. Understanding the nature of chemical bonds can greatly help in identifying the type of bonding in a given compound.
