Question Analysis
This question tests the student's ability to calculate the electronegativity difference (ΔEN) and use it to determine the type of chemical bond.

Key Concept Explanation
The electronegativity difference (ΔEN) between two elements is calculated by subtracting the smaller electronegativity value from the larger one. The ΔEN helps predict the type of bond: ionic (ΔEN > 1.7), nonpolar covalent (ΔEN = 0–0.4), and polar covalent (ΔEN = 0.4–1.7).

Step-by-step Solution
1. Identify the electronegativity values: EN(N) = 3.04, EN(O) = 3.44.
2. Calculate the ΔEN: ΔEN = 3.44 - 3.04 = 0.40.
3. Determine the type of bond based on the ΔEN: Since Δ...
