Moissan made a solution of hydrofluoric (HF) acid in potassium hydrogen fluoride (KHF 2 ). He then cooled the solution to -23°C (-9.4°F) and passed an electric current through it. A gas appeared at one end of the apparatus. He gave the name fluorine to the new element. The name...

The astatine element is located in period 6 group 17 on the periodic table. It belongs to the halogen group, which is a group that consists of the following electronegative elements: Fluorine Chlorine Bromine Iodine Figure 1: Astatine is in period 6 group 17, it belongs to the ...
The name Fluorite comes from the Latin word “fluere,” which means “to flow,” and the name of the element Fluorine is derived from the same. Fluorite was given this name because it is often used as a flux in smelting. A flux is a material added to hot metal liquids to improve the...
of astatine are radioactive and decay into other elements. For this reason, the element's properties are difficult to study. Whatisknown is that it has properties similar to those of the other halogens—fluorine, chlorine, bromine,andiodine.Because it is so rare, it has essentially no uses....
Uses of Aluminum Fluoride Lesson Summary Frequently Asked Questions Is AlF3 ionic or covalent? Aluminum fluoride is a covalent compound because the Al-F bonds are covalent bonds. Aluminum has a valency of three, it is sharing these three electrons with each fluorine atom. ...
