The correct order of electronegativity for given elements is

Options

A $P > Br > C > At$
B $Br > P > At > C$
C $Br > C > At > P$
D $C > P > At > Br$

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.
