Fluorine is the most reactive of the halogens because it is at the top of the halogen group, which is the second to right group on the periodic table. With halogens, the higher an element is in the column, the more reactive it is.Continue Reading
Halogens are reactive because the outer shells that orbit the nucleus lack electrons. This makes them eager to grab electrons from wherever they can get them.
Fluorine, whose atomic number is 9, is a violently reactive element. It will even attack glass and noble gases, which are considered inert. Even water explodes when exposed to fluorine. Because of its reactivity, fluorine is never found free in nature, but is found as some type of fluoride.
At standard pressure and temperature, fluorine is a pale yellow, poison gas that should not be handled by a non-professional and should certainly not be inhaled or ingested. However, when fluorine is present as fluoride, it can be quite beneficial. Calcium fluoride is used as a flux in the metal industry, and pure crystals are used as prisms. It also produces hydrofluoric acid, which is used in the manufacture of ceramics. Stannous fluoride, a compound of tin and fluorine, protects tooth enamel.Learn more about Chemistry
Arsenic is not particularly reactive though yellow arsenic is the most reactive and reacts with halogens under controlled conditions, fluorine and slowly with air (oxidization only). Arsenic does not react with water and is not explosive.Full Answer >
Some elements on the periodic table are oxygen, helium, arsenic and fluorine. Oxygen is an odorless, tasteless and colorless gas at room temperature, but is bright blue as a liquid. Oxygen is a very reactive element and is paramagnetic, which means it has unpaired electrons.Full Answer >
The 13 elements that are room temperature gases are radon (Rn), xenon (Xe), krypton (Kr), argon (Ar), chlorine (Cl), neon (Ne), fluorine (F), oxygen (O), nitrogen (N), helium (He) and hydrogen (H). Most non-metals in the periodic table have a gaseous elemental form.Full Answer >
Fluorine is a nonmetal that belongs to the family of elements called halogens. The symbol of fluorine is F, and its atomic weight is 18.9984032 atomic mass units or grams per mole.Full Answer >
