Fluorine is used as a radioactive tracer in PET Scans mostly as Fluorodeoxyglucose (more precisely 2-Deoxy-2-fluoro-D-glucose or FDG for short), which is a glucose analogue and is taken up by body cells that are high users of glucose such as brain and cancer cells. The presence of Fluorine in the molecule inhibits the body metabolising it as a normal glucose molecule. Once the Fluorine has decayed to Oxygen 18 the normal metabolic process proceeds. A typical dose is 5 - 10 millicuries or 200 to 400 MBq administered by saline drip. The patient is scanned an hour later during which the patient should avoid activity so that the FDG does not go to active muscles

What type of element is the most reactive of all nonmetals?
Fluroine is the most reactive non-metal.
Does fluroine lose or gain electrons?
Fluorine (F) gains 1 electron to fill its second energy level with 8 electrons.
What are cfcs used for?
Its used in the compressors of refrigerators and air- conditioners
What is Crocoite used for?
Crocoite is mainly used as a mineral specimen. It used to be used as a minor ore of chromium, but it is now too rare to be used for that.It is on wikipedia too
What is the use of acetal?
dilute ethanoic acid is used as a preservative in the preparation of pickles.it is used for making cellulose acetate which is an important artificial fibre.it is used in the manufacture of acetone and esters used in perfumes.it is used in the preparation of dyes.it is used to coaggulate rubber from latex.it is used for making white lead which is used as a white paint.it is used as a chemical reagent in chemistry lab.
How many electrons does fluroine have?
9
What is needed in significant amounts by the body?
fluroine
Is potassium and fluroine covalent or ionic bonding?
Ionic
What is the atomic number of fluroine?
Fluorine is a non meta element. Atomic number of it is 9.
What type of element is the most reactive of all nonmetals?
Fluroine is the most reactive non-metal.
What does hydrogen fluoride electron dot diagram look like?
One bond and 6 unpaired electrons around fluroine.
Does fluroine lose or gain electrons?
Fluorine (F) gains 1 electron to fill its second energy level with 8 electrons.
What are some examples of industries?
Industries include what makes the country run. Some examples include oil, zinc, sulfur, fluroine, pashmina, etc.
What mineral is needed in largest amounts according to the RDA?
Calcium, phosphorus, sodium, chloride, potassium, magnesium, and sulfur.
Is acetic acid hydrofluoro acid?
Acetic acid's systematic name is ethanoic acid (CH3COOH)Hydrofluoric acid's molecular formula is HF a combination of hydrogen and fluroine, which is acidic dissolved in water.
What would happen if Fluroine atom loses a proton?
When fluorine gains its last electron to gain a full outer-shell, fluorine becomes a negatively (because its a non-metal) charged atom/ion. Ionic features: -three dimensional atoms with strong bonds. -Higher melting and boiling points -F^2 -1
Why electron affinity of fluorine is large?
Electron affinity of an element is defined as the energy released by adding an electron to a gaseous atom of the element. With the electronic configuration of the fluroine atom being [Ne] 2s2 2p5, it needs just one more electron to form the fluoride ion (F-) which has the noble gas structure and is much more stable.
