Question Analysis
This question tests the student's understanding of the periodic trend in electronegativity across a period.

Key Concept Explanation
Electronegativity generally increases across a period from left to right due to the increasing nuclear charge and decreasing atomic radius.

Step-by-step Solution
1. Recall the periodic trend: Electronegativity increases across a period from left to right.
2. Understand the reason: The increasing nuclear charge and decreasing atomic radius make it easier for the nucleus to attract elec...
