What did Henri moissan discover?
FluorineHenri Moissan / DiscoveredFluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative element, it is extremely reactive, as it reacts with all other elements except for argon, neon, and helium. Wikipedia
How did Joseph Henri moissan discover fluorine?
He took up the study of fluorine compounds in 1884. Two years later, by electrolyzing a solution of potassium fluoride in hydrofluoric acid, he prepared the highly reactive gas fluorine. He made a full study of the properties of the element and its reactions with other elements.
How did H moissan Discover Carbon?
Moissan went on to study fluorine chemistry in great detail, contributed to the development of the electric arc furnace and attempted to use pressure to synthesize diamonds from the more common form of carbon. In 1893, Moissan began studying fragments of a meteorite found in Meteor Crater near Diablo Canyon in Arizona.
How old was Henri moissan when he discovered fluorine?
On Nov. 12, the academy bestowed the 1906 chemistry prize on Moissan, 54, “in recognition of the great services rendered by him in his investigation of the element fluorine, and for the adoption in the service of science of the electric furnace called after him.”

Did Henri moissan Discover Carbon?
In 1892, Moissan theorized that diamonds could be synthesized by crystallizing carbon under pressure from molten iron. He designed and developed the electric-arc furnace, attaining temperatures up to 3,500°C, to assist him in work which led to the production of tiny artificial stones.
What country did Henri moissan discover fluorine?
France
It was only in 1884 that Henri Moissan began to concentrate solely on isolating fluorine, a halogen discovered in the early years of the nineteenth century thanks to the work of A.M. Ampère in France and H. Davy in England.
When did Henri moissan discover fluorine?
1886
Henri Moissan, a French chemist, finally isolated fluorine in 1886 — after being poisoned several times in his pursuit. He was awarded the Nobel Prize in 1906 for the isolating fluorine by electrolysis of dry potassium hydrogen fluoride (KHF2) and dry hydrofluoric acid.
When was Henri moissan born?

Henri Moissan was born in Paris on September 28, 1852. His advanced education began in the Collège de Meaux and later in Edmond Frémy’s laboratory at the Musée d’Histoire Naturelle, where he attended lectures by E.H. Sainte-Claire Deville and Henri Debray.
