Electronegativity is a measure of an atom's ability to attract electrons to itself when it is part of a chemical bond. The electronegativity trend is generally observed to be a progression from low electronegativities at the bottom left of the periodic table to high electronegativities at the top right of the periodic table.
The noble gases, which are located at the far right of the periodic table, are not typically involved in chemical bonding and therefore do not generally exhibit the same trends in electronegativity as other elements.
This is because the outermost electron shells of the noble gases are typically fully filled, which makes them relatively stable and unreactive. As a result, noble gases are not expected to exhibit the same trends in electronegativity as other elements.
