Fluorine is an extremely reactive element due to its high electronegativity and small atomic size. It forms compounds with virtually all other elements, except for a few noble gases. Fluorine is used in many industrial processes, such as in the production of uranium, aluminum, and sulfur hexafluoride. It is also used in dental products to prevent tooth decay, and in the production of Teflon, a non-stick coating used in cooking utensils. Handling of fluorine and its compounds requires extensive safety precautions due to their highly reactive nature.
