what sets xenon and krypton apart from the other noble gasses that enables them to have higher electronegativites?

Of course they have. E.g. Mulliken's EN can be derived from measured electron affinities and ionisation energies, seeRaghav Gupta said:Noble gases do not have electro negativity.
Xenon and krypton are both located in group 18 of the periodic table, which is known as the noble gas group. This group is characterized by having a full outer electron shell, making them stable and unreactive. However, xenon and krypton have larger atomic radii and more electron shells than the other noble gases, which results in a stronger attraction between the positively charged nucleus and the negatively charged electrons, giving them a higher electronegativity.
The high electronegativity of xenon and krypton can be attributed to their large atomic radii and the number of electron shells they possess. Additionally, these elements have a high effective nuclear charge, meaning that the positive charge of the nucleus is able to attract the electrons more strongly.
Xenon and krypton have higher electronegativities compared to other noble gases, but they are still relatively low compared to other elements in the periodic table. This is because the noble gases have a full outer electron shell, making them less likely to attract additional electrons. Compared to non-noble gas elements, the electronegativity of xenon and krypton is relatively low due to their large atomic radii.
The high electronegativity of xenon and krypton makes them less reactive compared to other elements. This is because they have a strong attraction for electrons, making it difficult for them to form chemical bonds with other elements. However, they can still form compounds under certain conditions, such as with highly electronegative elements like fluorine.
The electronegativity of an element is a fundamental property that cannot be altered. However, it can be affected by external factors such as the presence of other elements and their electronegativities. Additionally, the electronegativity of xenon and krypton can be measured and compared to other elements, but it cannot be changed or manipulated.
