Whose discovery first isolated fluorine, the most reactive element?
Quick Answer
Henri Moissan’s. In 1886, he isolated fluorine by electrolyzing a mixture of hydrogen fluoride and potassium fluoride.
The Full Story
Henri Moissan succeeded where many chemists had failed by isolating fluorine in 1886. He used a carefully designed low-temperature electrolysis setup with hydrogen fluoride and potassium fluoride. Fluorine is the most reactive element in the periodic table, which made it notoriously difficult and dangerous to isolate. Moissan’s success was a major chemical milestone and earned him the 1906 Nobel Prize in Chemistry. His method opened the door to fluorine chemistry, though much safer techniques were later developed.
