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

Re: Noble Gases
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

Re: Noble Gases
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!

Re: Noble Gases
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.

Re: Noble Gases
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!

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

Re: Noble Gases
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.

Re: Noble Gases
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.

Re: Noble Gases
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.

Re: Noble Gases
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.

Re: Noble Gases
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.

Re: Noble Gases
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.

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.

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

Re: Noble Gases
Noble Gases are generally not included in any of the trends of the Periodic Table, since each of the Noble gases have full octet of electrons, or a full valence shell. Because of this, they already have very low electronegativity.

Re: Noble Gases
No, neon gases aren't included in electronegativity. This is because they've filled their valence shells so they don't need to attract electrons and electronegativity is the ability of an atom to gain an electron.

Re: Noble Gases
Noble gases are stable and have already reached full octet (full valence shell). Therefore, Neon gas, being a noble gas, is not included in electronegativity (or electron affinity and atomic radius for that matter).

Re: Noble Gases
Noble gases are usually left out of periodic table trends as they have a full octet and therefore do not want to gain any or lose any electrons. So, they are not used in periodic table trends such as electronegativity.
Re: Noble Gases
I do not think noble gases should be included.. This is because noble gas a complete octet, they do not need to gain more electrons. Xenon on the other hand has a large atomic radius, making it less tightly packed thus has weak control over its electrons.

Re: Noble Gases
Noble gases already have eight electrons in their outer shells (full octet). So, they won’t be able to attract any more electrons.

Re: Noble Gases
Noble gasses usually aren't considered. Since they have a full octet, they don't naturally accept electrons due to the energy it would take to accept. However, it can happen in labs and special situations

Re: Noble Gases
If asked to compare an element that is in the group to the left of the noble gas, would that element have a higher electronegativity then?

in comparison to noble gases I believe the answer would be yes since those elements do not have a full octet like the noble gases do.

Re: Noble Gases
As many have already stated, Noble Gases are exempt from the electronegativity trend, as they already have a full octet and are within the most stable position.

Re: Noble Gases
Noble gases have a full valence electron shell, so they do not pair with anything unless electrons are forced onto it. Which requires quite a bit of energy and the electron is lost rapidly.

Re: Noble Gases
No, they are omitted. This is due to noble gases having a full octet. A full octet means that the element or compound is not reactive. If these full octet elements were to add an electron, it would require energy and, thus, the electron affinity for it would be negative.

Re: Noble Gases
Noble Gases are exceptions from the rules because they are out of the running so to speak for gaining/losing electrons
Re: Noble Gases
Electronegativity is the atom's ability to attract electrons within a bond. Since noble gases already have a full valence shell of electrons and are stable, they have no need for attracting electrons so no, they do not have electronegativity.

Re: Noble Gases
Noble gases are not counted for their electronegativity because unlike the other elements, they have a perfect octet, so it would be unfavorable for them to gain another electron.

nobel gases have full octet, thus they are not included for electronegativity purposes

Re: Noble Gases
Would noble gases follow the trend for first ionization energy? It seems like it would take a lot of energy to remove an electron from the full valence shell.
