Argon fluorohydride, with the chemical formula HArF, is an interesting hypothetical chemical compound composed of argon (Ar), hydrogen (H), and fluorine (F) atoms. It is a member of the family of noble gas compounds, which are compounds containing noble gases, such as argon, xenon, and krypton, bonded to other elements.

The existence of argon fluorohydride was first theorized in the 1970s and has been the subject of theoretical studies and computational chemistry. However, as of my last knowledge update in September 2021, argon fluorohydride had not been experimentally synthesized or observed.

Noble gas compounds are challenging to stabilize due to the inherent stability of noble gas atoms and their reluctance to form chemical bonds with other elements. Nonetheless, the theoretical study of such compounds helps advance our understanding of chemical bonding and the behavior of elements under extreme conditions.
