Question Analysis
This question tests the student's understanding of the periodic trends in electronegativity and the factors that influence these trends.

Key Concept Explanation
Electronegativity is the relative ability of an atom to attract shared electrons in a chemical bond.
As you move from left to right across a period, the nuclear charge (number of protons) increases, while the atomic radius decreases.
These changes lead to a stronger attraction for electrons, thus increasing electronegativity.

Step-by-step Solution
1. Identify the key concept: Electronegativity trends across a period.
2. Recall that electronegativity increases from left to right across a per...
