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

Key Concept Explanation
The type of bond formed between two elements depends on the electronegativity difference (ΔEN).
A ΔEN of 0–0.4 results in a nonpolar covalent bond, 0.4–1.7 results in a polar covalent bond, and >1.7 results in an ionic bond.

Step-by-step Solution
1. Identify the electronegativity values for elements X and Y.
2. Calculate the ΔEN: ΔEN = 3.0 - 2.5 = 0.5
3. ...
