The inert gases are typical non-metals in many ways. They are colourless, odourless gases which have low melting and boiling points. They are poor conductors of heat and electricity even when in the liquid form. Just like in other groups of the periodic table, there are clear trends in the melting and ...
WebThe rare gases, also known as the noble gases or the inert gases, are a group of six gaseous elements found in small amounts in the atmosphere: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).

Web17 dec. 2014 · Noble gases usually do not form strong bonds between their atoms - it takes a fair amount of energy to dimerise them into excimers, but those are short-lived excited molecules. Thanks to excitation, shells of the atoms aren't closed and they react, but very quickly they lose energy and become separate atoms. With exception of weakly bound X …
