Using periodic trends, arrange the following atoms in order of increasing electronegativity: F, O, S, As

Question

Quizplus · Accepted Answer

Electronegativity generally increases across a period (from left to right) and decreases down a group (from top to bottom) on the periodic table. As is located in the 5th period and 15th group, S is in the 3rd period and 16th group, O is in the 2nd period and 16th group, and F is in the 2nd period and 17th group. Therefore, the order of increasing electronegativity is As < S < O < F.
