Question Analysis
This question evaluates the understanding of periodic trends, specifically the trend in electronegativity across a period.

Key Concept Explanation
Electronegativity is the relative ability of an atom in a chemical compound to attract shared electrons to itself. As you move from left to right across a period, the atomic radius decreases and the nuclear charge increases, leading to an increase in electronegativity.

Step-by-step Solution
1. Recall the trend in electronegativity across a period.
2. Understand that electronegativity ...
