Due to its full valence electron shell and weak intermolecular forces, it is very difficult for argon to form molecules. For this reason it is usually considered one of the most inert noble gases. It is only recently that scientist have been able to form molecules using argon, the most notable of which is HArF. This was accomplished by mixing argon with ultraviolet light and hydrogen fluoride. It is predicted that there are more molecules that we may be able to create soon as well, such as HArCl.
