WebFluoride is an essential ion for animals, strengthening teeth and bones. It is added to drinking water in some areas. The presence of fluorides below 2 parts per million in drinking water is believed to prevent dental cavities. However, above this concentration it may cause children’s tooth enamel to become mottled. WebFluorine is the most reactive element in Group 7. In fact it is the most reactive of all non-metals. ... The animation below demonstrates the trend in reactivity by the reaction of the halogens with iron wool. Reaction with alkali metals. The halogens react with metals to make salts called metal halides. metal + halogen ——→ metal halide.

WebFluorine (F 2 ), a highly toxic, colorless gas, is the most reactive element known so reactive that asbestos, water, and silicon burst into flame in its presence. It is so reactive it even forms compounds with Kr, Xe, and Rn, elements that were once thought to be inert. WebAug 15, 2024 · The halogen gases vary in their reactions with water due to their different electronegativities. Because fluorine (\(\ce{F2}\)) is so electronegative, it can displace oxygen gas from water. The products of this reaction include oxygen gas and hydrogen fluoride. The hydrogen halides react with water to form hydrohalic acids (\(\ce{HX}\)). … culture and animals foundation
