Question Analysis
This question tests the student's understanding of periodic trends in electronegativity and their ability to arrange elements in order of increasing electronegativity.

Key Concept Explanation
Electronegativity generally increases as you move from left to right across a period. In the same period, sodium (Na) is to the left, magnesium (Mg) is in the middle, and aluminum (Al) is to the right.

Step-by-step Solution
1. Identify the positions of sodium (Na), magnesium (Mg), and aluminum (Al) in the periodic table.
2. Recognize that sodium (Na) is to the left, magnesium (Mg) is in the middle, and aluminum (Al) is to the right in the same pe...
