Electronegativity in Fluorine
I understand that from left to right across a period of elements, electronegativity increases. From top to bottom down a group, electronegativity increases. Why is it that fluorine goes against this trend and is considered to be the most electronegative element?

Re: Electronegativity in Fluorine
Hi,
Quick correction! Electronegativity DECREASES down a group (from top to bottom of a column). This is why fluorine is considered the most electronegative element in the periodic table.
Here is a diagram that illustrates the electronegativity trend in the periodic table:
Hope this helps! :)

Re: Electronegativity in Fluorine
Yup, fluorine is the most electronegative element as stated previously, and in fact, I use this as an anchor of understanding periodicity of electronegativity. As you can see, fluorine is in the top right area of the periodic table, so a good way to remember this trend is to think of fluorine's position in the table and that electronegativity increases across a period and up a group.

Hi!
Thinking electron-wise, Fluorine has 5 electrons in the p-orbital and is missing one electron to complete the octet. Hence, it holds on to the electrons very tightly.
I hope this helps
