Please let know how is Electronegativity value in Halogen family? I am really unclear. Thank you.

Here are the electronegativities of the halogens.
##”F” = color(white)(l)3.98##
##”Cl” = 3.16##
##”Br” = 2.96##
##”I” = color(white)(ll)2.66##
##”At” = 2.2##
Below is a diagram of trends in .
The trends for the halogens (in Group 17) are shown by the yellow arrow.
The electronegativities increase from the bottom to the top of the Group, and ##”F”## is the most electronegative atom in the Periodic Table.
Electronegativity tends to increase from left to right in a Row of the Periodic Table.
With the exception of astatine (in Row 6), each halogen has the highest electronegativity of any element in its Row.
