Question Analysis
This question assesses the student's ability to determine the type of chemical bond formed between two elements based on their electronegativity difference (ΔEN).

Key Concept Explanation
The type of bond formed between two atoms depends on their electronegativity difference (ΔEN).
If ΔEN is greater than 1.7, the bond is ionic.
If ΔEN is between 0.4 and 1.7, the bond is polar covalent.
If ΔEN is less than 0.4, the bond is nonpolar covalent.

Step-by-step Solution
1. Calculate the electronegativity difference (ΔEN) for each pair of elements.
2. For Carbon (C) and Nitrogen (N): ΔEN = 3.04 - 2.55 = 0.49 (polar covalent)
3. For Lithium (Li) and Fluorine...
