Nonmetals have a stronger "pull" on their electrons because they are closer to having a full valence (outer) shell, making them stable.

The more valence electrons an element has, the more electronegative it is likely to be due to this "pull." Also, the further the negatively charged valence electrons are away from the positively charged nucleus, the weaker the attraction. Therefore more massive elements are generally less electronegative than their similarly-charged counterparts.
