Arrange aluminum, boron, nitrogen, and phosphorous in order of increasing electronegativity.

Question

Quizplus · Accepted Answer

Electronegativity increases across a period from left to right and decreases down a group in the periodic table. Given the elements aluminum (Al), boron (B), nitrogen (N), and phosphorous (P), boron is to the left of aluminum in the same period, indicating it is less electronegative. Phosphorous is below nitrogen in the same group, making it less electronegative than nitrogen. Therefore, the correct order from least to most electronegative is Al < B < P < N.
