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.
