# A student investigates the chemical bonding in two binary compounds, \(\text{KF}\) and \(\text{NF}_3\).

| Compound with greater ionic character | Justification based on periodic trends |
| :—: | :—: |

Which of the following rows correctly identifies the compound with the greater ionic character and provides the correct justification?

A student investigates the chemical bonding in two binary compounds, \(\text{KF}\) and \(\text{NF}_3\).

| Compound with greater ionic character | Justification based on periodic trends |
| :---: | :---: |

Which of the following rows correctly identifies the compound with the greater ionic character and provides the correct justification?

- **A.** | \(\text{KF}\) | \(\text{K}\) has a higher electronegativity than \(\text{N}\), resulting in a stronger attraction for valence electrons. |
- **B.** | \(\text{KF}\) | The difference in electronegativity between \(\text{K}\) and \(\text{F}\) is greater than the difference in electronegativity between \(\text{N}\) and \(\text{F}\). |
- **C.** | \(\text{NF}_3\) | The difference in electronegativity between \(\text{N}\) and \(\text{F}\) is greater because \(\text{N}\) and \(\text{F}\) are both nonmetals in the same period. |
- **D.** | \(\text{NF}_3\) | \(\text{N}\) has a lower electronegativity than \(\text{K}\), resulting in a greater transfer of valence electrons to \(\text{F}\). |
