Fluorine has a rich chemistry, encompassing organic and inorganic domains. It combines with metals, nonmetals, metalloids, and most noble gases. [97] Fluorine's high electron affinity results in a preference for ionic bonding; when it forms covalent bonds, these are polar, and almost always single. [98] [99] [note 10]
The noble metals ruthenium, rhodium, palladium, platinum, and gold react least readily, requiring pure fluorine gas at 300–450 °C (575–850 °F). [14] Fluorine reacts explosively with hydrogen in a manner similar to that of alkali metals. [15] The halogens react readily with fluorine gas [16] as does the heavy noble gas radon. [17]
However, heavier noble gases such as radon are held less firmly together by electromagnetic force than lighter noble gases such as helium, making it easier to remove outer electrons from heavy noble gases. As a result of a full shell, the noble gases can be used in conjunction with the electron configuration notation to form the noble gas ...
Structure of a noble-gas atom caged within a buckminsterfullerene (C 60) molecule. Noble gases can also form endohedral fullerene compounds where the noble gas atom is trapped inside a fullerene molecule. In 1993, it was discovered that when C 60 is exposed to a pressure of around 3 bar of He or Ne, the complexes He@C 60 and Ne@C 60 are formed ...

Noble gas configuration is the electron configuration of noble gases. The basis of all chemical reactions is the tendency of chemical elements to acquire stability . Main-group atoms generally obey the octet rule , while transition metals generally obey the 18-electron rule .
They are said to acquire a noble gas configuration, or a full electron configuration. It is now known that most of these gases in fact do react to form chemical compounds, such as xenon tetrafluoride. Hence, they have been renamed to 'noble gases', as the only two of these we know truly to be inert are helium and neon.
As an example, in the case of fluorine, the electronic configuration is 1s 2 2s 2 2p 5. Discard the full subshells and keep the 2p 5 part. ... especially noble gas atoms.
