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.
Besides, what is the chemical formula of fluorine gas?
“F” is the symbol for the chemical element Fluorine, not its chemical formula. The term “chemical formula” is used for compounds/ molecules of elements. Since Fluorine exists as diatomic molecule, its chemical formula is F2!
What are the dangers of fluorine gas?
As a result humans are exposed to fluorine through food and drinking water and by breathing air. Fluorine gas is released in the industries. This gas is very dangerous, as it can cause death at very high concentrations. At low concentrations it causes eye and nose irritations.
What is the chemical f2?
Fluorine is a nonmetallic, diatomic gas that is a trace element and member of the halogen family. It is used in dentistry as fluoride (FLUORIDES) to prevent dental caries. Fluorides, hydrogen fluoride, and fluorine are chemically related.
How reactive is fluorine?
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.
What family does fluorine belong to?
You should know that fluorine is classified as a halogen and you may find fluorine as the first chemical element, in the group VII A or 17, in periodic table. You also may find in this group the following halogens: chlorine, bromine, iodine, astatine and ununseptium.
How much is fluorine?

What is the family of fluorine?
In the second column from the right side of the periodic table, you will find Group Seventeen (Group XVII). This column is the home of the halogen family of elements. Who is in this family? The elements included are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
Is fluorine metal?
Many nonmetals are extremely greedy for electrons and will take them from metals. In these reactions, a nonmetal like nitrogen, oxygen, fluorine, chlorine, phosphorus, bromine, or sulfur will attack a metal and steal its electrons. The nonmetal, with its surplus of electrons, is now a ‘negatively’ charged ion.
What is the history of fluorine?
The name “fluorite” (and later “fluorine”) derives from Agricola’s invented Latin terminology. In the late 18th century, hydrofluoric acid was discovered. By the early 19th century, it was recognized that fluorine was a bound element within compounds, similar to chlorine. Fluorite was determined to be calcium fluoride.
How many protons and neutrons are in fluorine?
How many (i) protons, (ii) electrons and (iii) neutrons does a neutral fluorine atom have? 9 (same number as the of protons), 10 (19 9) isotopes 23 may 2012. Docx thephysicsteacher. If an atom has 9 protons and 10 neutrons, what is its atomic number the mass of fluorine?
Where is fluorine commonly found on Earth?
The main mining areas for fluorite are China, Mexico and Western Europe. Fluorine occurs naturally in the earth’s crust where it can be found in rocks, coal and clay. Fluorides are released into the air in wind-blown soil. Fluorine is the 13th most aboundant element in the Earth’s crust: 950 ppm are contanined in it.
Is fluorine found in toothpaste?
Sodium fluoride (NaF), stannous(II) fluoride (SnF2) and sodium monofluorophosphate (Na2PO3F) are all fluorine compounds added to toothpaste, also to help prevent tooth decay. Hydrofluoric acid (HF) is used to etch glass, including most of the glass used in light bulbs.
What is fluorine named after?
FluorineGeneral propertiesNamingafter the mineral fluorite, itself named after Latin fluo (to flow, in smelting)DiscoveryAndré-Marie Ampère (1810)First isolationHenri Moissan (June 26, 1886)Named byHumphry Davy
Is fluorine a liquid or a solid?
State at room temperature. Room temperature is usually taken as being 25°C. At this temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids. There is therefore a trend in state from gas to liquid to solid down the group.
Why is fluorine important and how is it used?
Fluorine is a pale yellow gas. It is highly and dangerously reactive. It is highly toxic because it reacts with the water in our body, producing very corrosive hydrofluoric acid. One of the most important aspects of fluorine is that it’s impossible to separate fluorine from its compounds in nature without chemicals.
What is the state of matter of fluorine?
The halogens exist, at room temperature, in all three states of matter – Gases such as Fluorine & Chlorine, Solids such as Iodine and Astatine and Liquid as in Bromine.
How did the element fluorine get its name?
The name fluorine is derived from the mineral fluorite which comes from the Latin word “fluere” meaning “to flow.” The name was suggested by English chemist Sir Humphry Davy.
Who discovered the element neon?
Morris M. Travers

What are some interesting facts about Neon?
Neon (Ne) is a colorless, non-metallic, very inert gas with an atomic number of ten. This member of the noble gas classification glows reddish orange in a vacuum tube. Interesting Neon Facts: While experimenting on liquid air, Sir William Ramsay and Morris Travers discovered neon in 1898.
What does the element chlorine look like?
Chlorine as an element is a pale green, poisonous gas with a suffocating odor. Chlorine as a chemical cleaner (in a solution with water) is a liquid, which is colorless with little odor, and a distinctly chemical taste.
What is the color of the chlorine?
The halogens darken in colour as the group is descended: thus, while fluorine is a pale yellow gas, chlorine is distinctly yellow-green.
