👤 whose

Whose discovery made fluorine the most reactive element on the periodic table?

Quick Answer

Henri Moissan’s. In 1886 he isolated fluorine, one of the most reactive elements known.

The Full Story

Henri Moissan succeeded in isolating fluorine in 1886 after many dangerous failed attempts by other chemists. Fluorine is extraordinarily reactive because it strongly attracts electrons, making it the most electronegative element. Moissan used special low-temperature and electrochemical techniques to obtain the gas, a major achievement in inorganic chemistry. He received the 1906 Nobel Prize in Chemistry for his work.
