Question 9
On the Pauling scale, which element has the highest electronegativity?
The right answer is the one marked above.
Fluorine, at 4.0 — the highest value on the scale.
The noble gases are not the answer, and the reason is worth knowing: they are given no value at all on the Pauling scale, because they show little tendency to form chemical bonds — and with no bond, there are no bonding electrons to attract.
