氟(F_2)是卤族中最活泼的化学元素,在通常条件下有刺鼻气味的淡黄色气体, 比空气稍重。氟在自然界中以氟化物形式分布于萤石、冰晶石和氟磷石灰中,不是稀有元素。1886年,法国化学家穆瓦桑,通过电解无水氟化氢,首次获得游离氟——单质氟。目前,科学家已将高纯单质氟用于火箭燃料作氧化剂,工业上用来制备氟化物,作为生产塑料、
Fluorine (F_2) is the most active chemical element in the halo family. It has a pungent yellowish gas under normal conditions, slightly heavier than air. Fluoride in nature in the form of fluoride in the distribution of fluorite, cryolite and lime phosphate, not a rare element. In 1886, the French chemist Moisangsang, for the first time, obtained free fluorine, a simple fluorine, by electrolysis of anhydrous hydrogen fluoride. At present, scientists have used high-purity elemental fluorine for rocket fuel as an oxidant, used industrially to prepare fluoride, as the production of plastic,
