Yes, Fluorine is an element. It comes in the form of a gas composed of F2 molecules. It is the most electronegative of all the elements and is extremely reactive.
Fluorine is an element. Its atoms are made of basically 3 fundamental particles (as is an atom of every other element just with different proportions) called electrons, protons and neutrons. Fluorine itself is a pure substance and contains no other particles except Fluorine atoms.
Yes, however, that is an extremely rare chemical combination. Krypton difluoride is a very powerful oxidizing substance
Fluorine is a halogen, so it reacts with Hydrogen, all of the Alkali Metals and all of the Alkali Earth Metals. There undoubtedly other reactions which I'm not aware of, so please feel free to add to this list if you know of any. There are few substances that Fluorine will not react with. It can react with any substance with which oxygen can react and even a few more such as glass.
Fluorine seems a likely answer
Fluorine.
Fluorine is certainly a substance, it is an element.
Fluorine is a chemical substance - a halogen.
Fluorine is a gaseous element which exists as diatomic molecules and every element is a pure substance.
Aluminum does react with fluorine gas (which is the most corrosive substance known to science).
F2 (fluorine) is an element and thus a pure substance. However a compound is a pure substance as well.
xylene is a mixture of ortho, meta and para methyl substituted toluene.
Fluoride on its own is not a substance, it is an ion. Specifically it is a fluorine atom with an extra electron, giving it a negative charge. To make a complete substance it must be paired with a positive ion. The "fluoride" in toothpaste is usually sodium fluoride, a compound of sodium and fluorine. Fluorine on its own is an element.
Whatever be the substance the one gram mole of that substance would have 6.023 x 1023 atoms or molecules or ions in it. Hence to get the mole just divide the number given by 6.023 x 1023
Fluorine is an element. Its atoms are made of basically 3 fundamental particles (as is an atom of every other element just with different proportions) called electrons, protons and neutrons. Fluorine itself is a pure substance and contains no other particles except Fluorine atoms.
If you mean the name of the element with the symbol F, it is Flourine
Elements are in the periodic table not substances, the most reactive of those elements would be Fluorine because of its electronegativity.
"Flourine" is a misspelling of fluorine, a chemical element that is a gas at standard temperature and pressure. The term "vapor" is usually restricted to a substance in the gas phase in equilibrium with a liquid that contains the liquid phase of the same substance. By this definition, fluorine could be a vapor only at a temperature far below standard temperature and pressure.
