Using periodic trends, arrange the following atoms in order of increasing electronegativity: S, Sr, P, Cs

Question

Quizplus · Accepted Answer

Electronegativity increases across a period from left to right and decreases down a group in the periodic table. Cs and Sr are in the same group with Cs being lower than Sr, hence Cs is less electronegative. S and P are in the same period with P being to the left of S, making S more electronegative than P. Therefore, the correct order from least to most electronegative is Cs < Sr < P < S.
