Fluorine F

Fluorine is the most electronegative of all elements and forms compounds with most other elements where fluorine is always in the -1 oxidation state. The video above shows the reactivity of fluorine and gives some information about this element. More information (in German) about fluorine can be found here. Elemental fluorine is very toxic, but some of its compounds, such as sodium fluoride, are added as additives in toothpaste. Table salt is also often mixed with fluorine-containing minerals.

Here she explains why Véronique Gouverneur, a professor at the University of Oxford (UK), is enthusiastic about fluorine.

halogens

The halogens form the 17th group of the periodic table. They include fluorine, chlorine, bromine, iodine and the radioactive astatine.

Tennes, which does not occur naturally, was added a few years ago as element number 117. Tennes was first artificially generated a few years ago at the Dubna Nuclear Research Center near Moscow. Its name refers to the US state of Tennessee, home to another research center, Oak Ridge National Laboratory, where various heavy elements have been synthesized.
