The correct order of electronegativity for given elements is

Options

  1. AP > Br > C > At
  2. BBr > P > At > C
  3. CBr > C > At > P
  4. DC > P > At > Br

Correct answer

C. Br > C > At > P

Step-by-step solution

On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left. Element Electronegativity P 2 . 1 C 2 . 5 Br 3 . 0 At 2 . 2 Hence, the correct order is Br > C > At > P.
