Fluorine is the most electronegative element on the periodic table

An intense electron attraction makes fluorine gas violently reactive with almost everything

Electronegativity quantifies how strongly an atom attracts shared bonding electrons toward itself. Fluorine possesses the highest electronegativity rating of nearly four on the Pauling scale due to its small atomic radius and high nuclear charge. Consequently, fluorine gas reacts aggressively with almost all organic and inorganic substances, including glass and noble gases.

Fluorine is the most electronegative element on the periodic table: the short answers

Where does this come from, and can I check it?
An intense electron attraction makes fluorine gas violently reactive with almost everything. The figure is taken from NIST, which is linked in full on this page. Every fact on Mondo Knows names its source rather than repeating an unsourced claim.
Is this really a science fact?
Yes. It sits on the Science shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.
What else can I read about it?
The links under the fact point to a quiz, game, puzzle or calculator on the same subject, and the shelf below shows related facts. The wording here is original, and quoted phrases are marked as quotations.
