According to the Pauling electronegativity scale, nitrogen has an electronegativity of 3.04 while chlorine has an electronegativity of 3.16, making chlorine slightly more electronegative than nitrogen. This is a fundamental chemical fact that requires no citation.
The claim compares the electronegativity of chlorine (3.16) and nitrogen (3.04) on the Pauling scale. This is a standard, universally accepted chemical fact taught in basic chemistry, qualifying it as common knowledge that does not require empirical papers to verify, despite the retrieval of unrelated chemistry papers in the search list.
