Does helium follow the electronegative trend of the periodic table or is it an exception to rule becuase of how the table of elements is set up?

I just answered this previously check this out


"This is the easiest of the exceptions. We have said that electronegativity increases to the right. This is true except that the trend does NOT include the noble gases. That means that fluorine has the highest electronegativity, not Ne or He. This is because the definition of electronegativity contains the phrases "in a covalent bond." Since the noble gases don't bond, they don't have electronegativities."

The noble gases do not get included in electronegativity due to the fact that they have 8 electrons already and do not need/want to attract any more. This means they wouldn't have an electronegativity by definition.
