Eleven elements are in gaseous state at room temperature Two elements are liquids at room temperature. They are bromine and mercury Elements gallium and cesium become liquids at a temperature slightly above room temperature Most elements are generally stable, a small amount of natural transformation of...
He showed that the interaction of PtF6 vapour in the presence of xenon gas at room temperature produced a yellow-orange solid compound then formulated as [Xe+][PtF6−]. (This compound is now known to be a mixture of [XeF+][PtF6−], [XeF+] [Pt2F11−], and PtF5.) Shortly ...

At room temperature Some Uses of Aluminium Metaland Alloys Pure aluminium is a silvery-white metal with many desirable properties: it is light, non-toxic, of pleasing appearance. and capable of takbg a high polish. It has a high thermal and electrical conductivity, excellent corrosion resistance...
At room temperature the stable form HCl to a minimum of 1.56g per 100 g at about is monoclinic a-Bi2O3 which has a polymeric 3~ HCl and then increases, presumably due to layer structure featuring distorted, 5-coordinate the formation of chloro-complexes. In neutral Bi in pseudo-...
A method for producing solid targets from materials which are normally gaseous at room temperature is described. The system, which is based on a closed cycle helium refregerator capable of a lowest temperature of 10 K, can be used for all gases except H, He and Ne. The apparatus has bee...
SAID PLANT IS EQUIPPED WITH SPECIAL DEVICES WHICH ALLOW AN ISOBARIC FILLING OF 10 CONTAINING ELEMENTS WITH GASEOUS FLUIDS. IN GENERAL, THE GASEOUS FLUIDS ARE DIFFICULT TO CONTROL, ESPECIALLY IN NATURAL THERMIC CONDITIONS AND IN PARTICULAR AT A HIGHER TEMPERATURE THAN 5' C BECAUSE OF THE FORMATION...
