Answer
Explanation:
Step1: Recall bond - type rules
Ionic bonds form between a metal and a non - metal. Polar covalent bonds form between non - metals with different electronegativities. Nonpolar covalent bonds form between identical non - metals.
Step2: Analyze NaCl
Sodium is a metal and chlorine is a non - metal, so it's an ionic bond. Sodium donates one valence electron to chlorine.
Step3: Analyze H₂O
Hydrogen and oxygen are non - metals. Oxygen is more electronegative than hydrogen, creating a polar covalent bond.
Step4: Analyze CO₂
Carbon and oxygen are non - metals. Oxygen is more electronegative than carbon, resulting in polar covalent bonds.
Step5: Analyze F₂
Two fluorine atoms (identical non - metals) share electrons equally, forming a nonpolar covalent bond.
Step6: Analyze MgO
Magnesium is a metal and oxygen is a non - metal, so it's an ionic bond.
Answer:
| Compound | Elements Involved | Bond Type | Draw the Bond What happens to the e⁻? |
|---|---|---|---|
| 14. NaCl | Sodium + Chlorine | Ionic | Na - Cl; the cation donates 1 valence e⁻ to the anion. |
| 15. H₂O | Hydrogen + Oxygen | Polar covalent | H - O - H; electrons are pulled towards oxygen. |
| 16. CO₂ | Carbon + Oxygen | Polar covalent | O = C = O; electrons are pulled towards oxygen. |
| 17. F₂ | Fluorine + Fluorine | Nonpolar covalent | F - F; electrons are shared equally. |
| 18. MgO | Magnesium + Oxygen | Ionic | Mg²⁺O²⁻; magnesium donates 2 valence e⁻ to oxygen. |
