Are neon gases included in electronegativity? And if so, does xenon have a higher electronegativity that fluorine?

Noble gases are generally not included in the periodic table trends. 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

The electronegativity scale we use is Pauling Electronegativity scale, and in this scale electronegativity of a neon atom has no data. 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 4.50.

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!

I like to consider electronegativity as how much an atom will hog an electron when it is bonded. Since Neon already has an octet, it won't want any more electrons so, hypothetically, it will have very low electronegativity.

Not usually, since they are perfect octets (have all orbitals filled depending on where it sits on the periodic table), they do not want to attract anymore electrons, nor lose them. They want to stay as stable as they are, so technically their electronegativity levels are very small to none and therefore, xenon does not have a higher electronegativity than fluorine. Fluorine stays the highest electronegative element because it wants to attract that extra electron to make it as stable as a noble gas since it has 7 valence electrons on its own. Hope that helps!

No, neon gases are not included in the electronegativity trend, so neon is not more electronegative than fluorine.

Noble gases are not included in the trend for electronegativity.

They are typically not included in the trend since the electronegativity trend is used for bonding. Noble gases already have full valence shells, so they tend not to bond with other elements, resulting in there not being a need for their inclusion in the trend.

Noble gases have no electronegativity because they already have a full octet

No, fluorine has the highest electronegativity in all the periodic table; the noble gases have a complete octet so they would not want another electron.

Noble gases are not included in the e-negativity trend, because they are already full (p6 electrons) they do not want to add any more, because that would make them unstable. The goal is always to be as stable as possible.

Since noble gases already have a full octet, they do not attract electrons. So , they are not included in electronegativity and fluorine is the most electronegative element on the periodic table.

Noble gases have very small electronegativites since they already have full octets.

Neon gas yes, is part of the normal electronegativity trends. Noble gasses, on the other hand, don't follow the pattern because they all already have filled valence shells.

Noble gases typically are not included in the periodic trends. For electronegativity, they would have a very low value due to their filled valence shells.

Does anyone have a viideo they think is a good reference for this topic?

They are usually not included. But Xenon, since it has such a large atomic radius, has very weak control over its valance electrons and therefore can bind with other elements.

Noble gases are not included in the electronegativity trend. In fact they are left out of most period trends.
