Complete the table below by writing the symbols for the cation and anion that make up each ionic compound. The first row has been completed for you.
The correct answer and explanation is:
Here is the completed table with the correct cation and anion symbols for each ionic compound:
| Ionic Compound | Cation Symbol | Anion Symbol |
|---|---|---|
| Sodium chloride (NaCl) | Na⁺ | Cl⁻ |
| Calcium bromide (CaBr₂) | Ca²⁺ | Br⁻ |
| Aluminum oxide (Al₂O₃) | Al³⁺ | O²⁻ |
| Magnesium nitrate (Mg(NO₃)₂) | Mg²⁺ | NO₃⁻ |
| Potassium sulfate (K₂SO₄) | K⁺ | SO₄²⁻ |
Explanation:
Ionic compounds are composed of positively charged ions (cations) and negatively charged ions (anions) that are held together by electrostatic forces. The charges of these ions must balance to create a neutral compound.
- Sodium chloride (NaCl):
- Sodium (Na) is a Group 1 metal, forming Na⁺.
- Chlorine (Cl) is a Group 17 nonmetal, forming Cl⁻.
- The 1:1 ratio balances the charges.
- Calcium bromide (CaBr₂):
- Calcium (Ca) is a Group 2 metal, forming Ca²⁺.
- Bromine (Br) is a Group 17 nonmetal, forming Br⁻.
- Two Br⁻ ions are needed to balance one Ca²⁺ ion.
- Aluminum oxide (Al₂O₃):
- Aluminum (Al) is a Group 13 metal, forming Al³⁺.
- Oxygen (O) is a Group 16 nonmetal, forming O²⁻.
- The ratio of Al³⁺ to O²⁻ is 2:3 to balance the total charge.
- Magnesium nitrate (Mg(NO₃)₂):
- Magnesium (Mg) is a Group 2 metal, forming Mg²⁺.
- Nitrate (NO₃⁻) is a polyatomic ion with a charge of -1.
- Two NO₃⁻ ions are needed to balance one Mg²⁺ ion.
- Potassium sulfate (K₂SO₄):
- Potassium (K) is a Group 1 metal, forming K⁺.
- Sulfate (SO₄²⁻) is a polyatomic ion with a charge of -2.
- Two K⁺ ions are required to balance one SO₄²⁻ ion.
Now, I will generate an image of the completed table.
Here is the image of the completed table, generated using DALL·E, OpenAI’s legacy image generation model. A new model will be rolling out in ChatGPT soon! Let me know if you need any modifications.
