Is fluorine F2 an element or compound?
Fluorine is the chemical element in the periodic table that has the symbol F and atomic number 9. Atomic fluorine is univalent and is the most chemically reactive and electronegative of all the elements. In its pure form, it is a poisonous, pale, yellow-green gas, with chemical formula F2.
Is fluorine An example of a compound?
Elemental fluorine (F2) is the most reactive element. Fluorine combines directly with all other elements, except nitrogen and the lighter noble gases. It also reacts with many compounds forming fluorides, and many organic compounds inflame and burn in the gas….Covalent compounds.

What element does fluorine belong to?
Halogen group
Fluorine (F) is the first element in the Halogen group (group 17) in the periodic table. Its atomic number is 9 and its atomic weight is 19, and it’s a gas at room temperature. It is the most electronegative element, given that it is the top element in the Halogen Group, and therefore is very reactive.
Is fluorine a pure substance?
An element is a substance that cannot be broken down into other substances through chemical means. There are 112 officially named elements and about 118 known elements. Most of these are natural, but some are man-made….Elements (ESAAA)

Is Chromium an element or compound?
chromium (Cr), chemical element of Group 6 (VIb) of the periodic table, a hard steel-gray metal that takes a high polish and is used in alloys to increase strength and corrosion resistance.
Is fluorine a polymer?
Traditionally, a fluoropolymer or fluoroplastic is defined as a polymer consisting of carbon (C) and fluorine (F) atoms. Sometimes these are referred to as perfluoropolymers to distinguish them from partially fluorinated polymers, fluoroelastomers, and other polymers that contain fluorine in their chemical structure.
What is Fluorine on the periodic table?
Fluorine: a small yet very adaptable element The most reactive, electronegative and oxidizing element, fluorine (F) is the first halogen in the periodic table. Fluorine is naturally present in the Earth’s crust where it is chiefly found in mineral form.
What are some interesting facts about fluorine?
Fluorine has the symbol F and is the ninth element in the periodic table. Normally, fluorine is a gas with a pale yellow color that is made up of diatomic molecules, F2. Fluorine is less common in stars than on Earth, where it is the 13th most frequently found element in the crust. The element is the lightest of the halogens.
What are two properties of fluorine?
Fluorine has two solid forms, α- and β-fluorine. The latter crystallizes at −220 °C (−364 °F) and is transparent and soft, with the same disordered cubic structure of freshly crystallized solid oxygen, unlike the orthorhombic systems of other solid halogens.
What is fluorine found in?
According to Lenntech, fluorine can naturally be found in water, air, and both plant and animal-based foods in small amounts . Larger amounts of fluorine are found in a few food products such as tea and shellfish.
Is fluoride a molecule?
Fluorine gas is the elemental form of the chemical element fluorine at standard temperature and pressure. Fluorine gas consists of molecules, rather than atoms of fluorine. Two atoms of fluorineform each molecule of chlorine, hence molecules of chlorine are said to be diatomic and the chemical symbol for fluorine gas is F 2.
