Fluorine-18 is created from bombardment of O-18 with a hydrogen ion in an accelerator or in a reactor with neutron bombardment of Lithium-6 followed by the resultant tritium combining with O-16 to form F-18. There may be places in the universe where a little of this may be going on but for all purposes it is not naturally occurring on Earth.
As for "abundance"... it depends on how many cyclotrons and target O-18 are used each day to create F-18 for FDG scanning and F-18 bone scanning.
With a 110 minute half-life, any given day's dose is gone by the next...
What else can I help you with?
Why was chlorine isolated before fluorine?
Chlorine was isolated before fluorine because it is more reactive and abundant, which made it easier to isolate and study. Fluorine is the most reactive of all elements and is rarely found in its elemental form in nature, making it more challenging to isolate.
Where on earth do you find fluorine?
Fluorine or Fluorite is natural to the earth's crust and is found in rocks, coal and other natural formations. It is the Earth's thirteenth most abundant element and around four million tons of it are extracted yearly from mines in Western Europe, China and Mexico.
What is the most abdunant halogen?
According to the source I found on the Web: "Of the halogens, fluorine has the highest crustal abundance (544 mg/kg) while iodine has the lowest (0.25 mg/kg), however, chlorine is by far the most abundant halogen in the cosmos." It's fluorine if you're only interested in the Earth's crust, or chlorine if you're interested in the whole solar system or an even wider field than that.
What is is the symbol for fluorine?
The chemical symbol for fluorine is F.
What type of bond is formed when you combine fluorine and fluorine?
A covalent bond is formed when fluorine combines with fluorine. This is because both fluorine atoms have similar electronegativities and share electrons to achieve a stable octet configuration.
How do you find the sum of fluorine?
The sum of elements like fluorine can be found by adding the atomic masses of its isotopes, weighted by their abundance in nature. The most abundant isotope of fluorine is fluorine-19, which has an atomic mass of 18.998403163 u. By accounting for the abundance of this isotope in nature, the average atomic mass of fluorine can be calculated, which is approximately 18.998 u.
What is the most abundant isotope of oxygen?
There is only one abundant isotope of fluorine and that is 19FFluorine-19 is the most common isotope, its abundance is classed as 100% because no other Fluorine isotopes exist in significant quantities. It is also the only stable Fluorine isotope.
Most abundant halogen?
The most abundant halogen on Earth is chlorine. It is commonly found in seawater, salt deposits, and as part of various minerals.
How abundant iodine is?
Iodine is very less abundant compared to fluorine and chlorine and it is found in seawater also with chlorides,bromides etc and certain forms of marine life also contain Iodine in their systems.Eg Seaweeds
Why was chlorine isolated before fluorine?
Chlorine was isolated before fluorine because it is more reactive and abundant, which made it easier to isolate and study. Fluorine is the most reactive of all elements and is rarely found in its elemental form in nature, making it more challenging to isolate.
What year was fluorine created?
Fluorine was discovered by Karl Scheele in 1771, recognized as a halogen in 1825, and included in Mendeleev's periodic table of 1869. Fluorine is so active that it existed only in compounds and all efforts to isolate the element failed. Because of its high corrosiveness/toxticity, early fluorine chemists died from fluorine poisoning and the element was dubbed "Tiger of Chemistry." Fluorine, from Latin "fleure" meaning to flow, is the 13th most abundant element in the earth's crust and the most reactive of all elements--it even forms compounds with noble gases.
What are most used elements?
The most commony used elements would be precious metals such as gold and silver. Copper, steel, uranium and fluorine are also commonly used.
Where on earth do you find fluorine?
Fluorine or Fluorite is natural to the earth's crust and is found in rocks, coal and other natural formations. It is the Earth's thirteenth most abundant element and around four million tons of it are extracted yearly from mines in Western Europe, China and Mexico.
How many elements are in a fluorine atom?
Fluorine is an element, s an atom of fluorine contains only one element - fluorine. However, the fluorine molecule consists of two atoms of fluorine.
How many atoms of fluorine in barium?
Fluorine is an element and barium is also an element. There is no fluorine in barium and not barium in fluorine.
What is the most abundant and useful halogen?
* Fluorine is found on Earth at about 585 mg/kg (crust) 1.3 mg/liter (ocean) * Chlorine is found on Earth at about 145 mg/kg (crust) 19400 mg/liter (ocean) * Bromine is found on Earth at about 2.4 mg/kg (crust) 67.3 mg/liter (ocean) * Iodine is found on Earth at about 0.45 mg/kg (crust) 0.06 mg/liter (ocean) * Astatine is not found on Earth in appreciable quantities (it has no stable isotopes) Earth's crust is about 8.5 * 1020 kg Earth's ocean is about 1.4 * 1018 liters This make fluorine the most abundant halogen *on Earth*, with chlorine 30% as abundant by mass, and 16% as abundant in number of atoms. Fluorine only has one stable isotope, whereas chlorine has two. Otherwise the race would not be even that close.
Is fluorine hard?
No. Fluorine is a gas.
