And if so, does xenon have a higher electronegativity that fluorine? Because noble gases already have a full valence shell completed octet , it would be unfavorable for them to gain any more electrons.

Because of this, noble gases tend to not react with other compounds. Of course there are other electronegativity scales which includes electronegativity of a neon atom. For example, Sanderson Electronegativity scale assigns a neon atom with an electronegativity of 4. However, each electronegativity scale has its own unique interpretation. You need to look up specific details of the interpretation before actually applying them in problem-solving.

Hope this can help! Re: Noble Gases Post by EvanWang » Mon Nov 11, am I like to consider electronegativity as how much an atom will hog an electron when it is bonded. Group: 8A. Atomic Radius. Ionic Radius. Atomic radius decreases from left to right within a period because of effective nuclear charge. As you move from left to right in a period, you are still in the same energy level which means the electron is still the same distance from the nucleus.

As you go down a group, the atomic radius increases because you are adding energy levels that are farther away from the nucleus. The Noble Gases do not have an ionic radius. This is because they don't form ions. Ions are charged particles, and atoms become charged particles when they gain or lose electrons. Atoms only gain or lose electrons in an attempt to establish an octet, or 8 valence electrons.

Now I don't understand why the first 3 noble gases have blank spaces instead of the electronegativities. If it is because their octet is complete then why doesn't the noble gases Kr, Xe and Rn have blank spaces under them?

They don't have values there because they aren't on the pauling scale of electronegativity, as they don't form any compounds with other elements. However, argon and neon can technically form compounds with other elements; it is just extremely unlikely. I don't think Helium can form any compounds other than with itself. The other noble gases also can react with fluorine As well as other elements , and make slightly more stable compounds.
