Because the noble gases have a complete outer shell of eight electrons (except for helium, which has just two),they are very resistant to forming bonds. ... In these lamps, a high voltage electrical discharge is passed through a tube of low-pressure neon gas. Are noble gases gases at ro...

Noble gases are colourless and odourless because they are monoatomic and non-reactive due to their full electron shells.Noble gases, which include helium, neon, argon, krypton, xenon, and radon, are found in Group 0 of the Periodic Table. They are known as inert gases because they are ver...

complete electrons in their outer shell. This complete number varies. For instance, the outer shell of Helium has 2 valence electrons while the outer shell of Xenon has 8 electrons. Nowadays, there remains to be a few noble gases because of the low chemical reactivity of these said gases. ...
some elements are gases (in a gas, there are larger spaces between the (molecules ). In the Noble Gases, each molecule has only one atom, because the atoms of these elements do not form chemical bonds with each other. In other gases, however, the molecules each have two atoms held toge...
