	==Synthesis==		== Synthesis ==
	This chemical was synthesized by mixing argon and ] on a ] surface at −265&nbsp;°C, and exposing the mixture to ultraviolet radiation. This caused the gases to combine.		This chemical was synthesized by mixing ] and ] on a ] surface at 8 K (−265 °C), and exposing the mixture to ultraviolet radiation. This caused the gases to combine.
	The ] of the resulting gas mixture shows that it definitely contains chemical bonds, albeit very weak ones; thus, it is argon hydrofluoride. Its chemical bonds are only stable if the substance is kept at temperatures below −256&nbsp;°C; upon warming, it decomposes into argon and hydrogen fluoride.		The ] of the resulting gas mixture shows that it definitely contains chemical bonds, albeit very weak ones; thus, it is argon fluorohydride, and not a ] or a mixture of argon and hydrogen fluoride. Its chemical bonds are stable only if the substance is kept at temperatures below 27 K (−246 °C); upon warming, it decomposes into argon and hydrogen fluoride.<ref name=ASAC/>
