What are three interesting facts about fluorine?
Fluorine is the most reactive and the most electronegative of all the elements. Fluorine is a pale yellow, diatomic, highly corrosive, flammable gas, with a pungent odor. It is the lightest halogen. It reacts violently with water to produce oxygen and the extremely corrosive hydrofluoric acid.
What are 5 uses of fluorine?
What are the uses of fluorine? Fluorine is critical for the production of nuclear material for nuclear power plants and for the insulation of electric towers. Hydrogen fluoride, a compound of fluorine, is used to etch glass. Fluorine, like Teflon, is used to make plastics and is also important in dental health.
What are 10 facts about gold?
- Gold is a chemical element.
- Compared to other metals, gold is less chemically reactive.
- Gold is a good conductor of electricity and heat.
- Gold is shiny, soft and dense.
- Gold is malleable enough for just 1 gram to be hammered into a sheet 1 square meter in size.
What is gold’s weakness?
Gold does not react with most chemicals but is attacked by chlorine, fluorine, aqua regia and cyanide and dissolves in mercury. In particular, gold is insoluble in nitric acid, which will dissolve most other metals. Nitric acid has long been used to confirm the presence of gold in items.
What are some interesting facts about fluorine ( F )?
Interesting facts about fluorine (F). Fluorine is the most receptive and most electronegative of all the chemical elements. The elements with which it doesn’t respond are oxygen, helium, neon, and argon. Fluorine is the only element which will shape compounds with noble gasses xenon, krypton, and radon.
