Flourine chemical state
WebFluorine is chemically recognised by the symbol F. It exists as the lightest amongst halogens. Fluorine is known to be the most reactive of the elements. This is because of … WebFluorine forms a great variety of chemical compounds, within which it always adopts an oxidation state of −1. With other atoms, fluorine forms either polar covalent bonds or ionic bonds. Most frequently, covalent bonds involving fluorine atoms are single bonds, although at least two examples of a higher order bond exist. Fluoride may act as a bridging ligand …
