QUESTION

# 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.
