noble gases

Why don't the noble gases have high electronegativity? It's farther on the periodic table than oxygen

Since higher electronegativity means that the element will have a stronger ability to attract electrons, noble gases have low electronegativity because they have a complete octet meaning they do not want to attract electrons

Purely based on periodicity, noble gases would be more electronegative than oxygen; however, all of the noble gases have a "filled" valence shell of eight electrons and they would not want to attract any more (it would not improve their stability or be energetically favorable to have one more electron than needed for a valence shell). Thus, noble gases do not generally attract electrons very strongly and thus have low electronegativities compared to other elements on the right side of the periodic table.
