This must be a typo of some sort. No, argon is not "a hydrogen," whatever that means.
You just get a gas mixture of argon and hydrogen. Being less dense, the hydrogen will rise above the argon.
Hydrogen, followed by oxygen. Argon is unreactive.
calcium is solid. argon and hydrogen are gases
Hydrogen
hydrogen or heliumhydrogen or helium
argon is used in lamps
You will get water and argon. Hydrogen an oxygen will readily and violently combine to form water. Argon is an inert gas, and so will not combine with other elements.
Hydrogen and hydrogen+fluorine.
Fluorine and hydrogen: to form argon fluorohydride.Hydrogen to form argonium or argon hydride.
Argon Fluorohydride (HArF). It was discovered in 2000 by scientist from the University of Helsinki in Finland. They shone a strong ultraviolet light on frozen argon particles that contained a small amount of hydrogen fluoride. The light split some of the hydrogen fluoride molecules into hydrogen and fluorine atoms, which then mixed with argon to form the new compound Argon Fluorohydride.
Argon (Ar), Hydrogen (H) and uranium (U) are chemical elements. Water (H2O) is a chemical compound.
