Get information about the properties shared by the noble gases or inert gases, plus a list of the elements in this group. The noble gases do not form positive or negative ions in the ordinary conditions, The elements of the atoms of which all the shells completely filled are called. Other characteristics of the noble gases are that they all conduct electricity, fluoresce, are odorless and colorless, and are used in many conditions when a stable element is needed to maintain a safe and constant environment. This chemical series contains helium, neon, argon, krypton, xenon, and radon.

In addition to the compounds where a noble gas atom is involved in a covalent bondnoble gases also form non-covalent compounds.
The clathratesfirst described in consist of a noble gas atom trapped within cavities of crystal lattices properties of inert gases certain organic and inorganic substances.
The essential condition for their formation is that the guest noble gas atoms must be of appropriate size to fit in the cavities of the host crystal lattice. For instance, argon, krypton, and xenon form clathrates with hydroquinonebut helium and neon properties of inert gases not because they are too small or insufficiently polarizable to be retained.
Bonding in such compounds can be explained using a three-center four-electron bond model. Argon plasma light bulb.
Krypton Similarly to argon, krypton can be found in properties of inert gases efficient windows. In addition, Krypton is used for high performance light bulbs, which have higher color temperatures and efficiency because the krypton reduces the rate of evaporation of the filament.
Xenon has also made it possible to obtain better x-rays with reduced amounts of radiation. When mixed with oxygen, it can enhance properties of inert gases contrast in CT imaging.
Plasma display panels PDPs using xenon as one of the fill gases may one day replace the large picture tubes in television and computer screens.

The formation and elimination of radioactive xenon decay products are factors in nuclear reactor control. All these noble gases are colorless, odorless and tasteless at standard temperature.
They have a low boiling point and all of them are gases at room temperature. In the periodic table, the boiling point of these elements increases as you come down.

Helium lies at the top of this list with a boiling point of Trends in physical properties Boiling point The properties of inert gases gases all have low boiling points. This is a typical property of non-metals. You can see from the graph that helium, at the top of group 0, has the lowest boiling point in the group.
