Resumen de Los Halógenos, ¿materia mineral farmacéutica?
In 1906 Henri Moissan was the first French person and first pharmacist to be awarded the Nobel Prize in Chemistry. It was the end of a large and gold chapter in which through more than a century, Scheele (1774), Courtois (1813), Balard (1823) and Moissan (1886), all of them pharmacists, isolated chlorine, iodine, bromine and fluorine, respectively. That is the reason why the title figures as a question. The elucidation of the halogen�s nature demolished the Lavoisier�s acidity theory. Some aspects of the life of the discoverers are given. Moissan was able to isolate and study fluorine, that savage beast among the elements.
