Which element has the lowest electronegativity?
Quick Answer
Francium is commonly cited as the least electronegative element, with an estimated Pauling electronegativity of about 0.7.
The Full Story
Francium is generally regarded as the least electronegative element on the periodic table, though it is extremely rare and radioactive, so its value is estimated rather than precisely measured. Its approximate electronegativity is about 0.7 on the Pauling scale. Because francium is so unstable and short-lived, its chemistry is difficult to study directly. In practice, cesium is often the best-known comparison for very low electronegativity among alkali metals.
