no·ble gas·es

(nō'bĕl gas'ĕz)
Elements in the zero group in the periodic series: helium, neon, argon, krypton, xenon, and radon.
Synonym(s): inert gases.

noble gases, a group of very stable elements, such as neon and argon, that do not easily react with other atoms because of their filled outer electron shell. Also called
inert gases.

According to EMPA, the basic idea of using the connection between the concentration of noble gases in the atmosphere and the average ocean temperature is correct and that the method works.
Of particular interest were changes in the gases' ability to conduct electricity as the pressure and temperature changed, because this can provide important information about the ways that the noble gases do actually interact with other materials in the extreme conditions of planetary interiors and stellar atmospheres.
The absence of inert noble gases tells scientists that the Saturnian system must have been warm when it formed; otherwise the noble gases would have been trapped in the icy building blocks that combined to form Titan.

One option to improve this situation is to polarize so-called "pure targets" such as HD and noble gases (He-3 or Xe-129) polarized targets.
When there's a line, patrons have the choice of waiting in the safety of the orchestra or, in the case of Adam Rapp's new play "Finer Noble Gases," lining up next to the actors who are engaged in one of those pre-performance performances that set the mood of the play that's about to start.
The scientists determined that discharges of radioactive noble gases and iodine isotopes had occurred.
Radon is a short-lived radioactive element belonging to the group of noble gases and results from the decay of radium and other radioactive elements.
In order of increasing density, the noble gases include helium, neon, argon, krypton, xenon, and radon.
As a result, chemists no longer liked to use the term inert gases, preferring noble gases as less likely to signify absolute inertness.
The experiments involve injection of noble gases like helium or neon at elevated temperatures.
Because most of the newer blowing agents have lower boiling points than CFCs, Dow Benelux in Terneuzen, The Netherlands, has developed high-pressure dispensing and nucleating machinery for making fine-cell foams using these new blowing agents and soluble nucleating gases such as nitrogen or other noble gases and liquids.
