Several characteristics of a gas are: chemical formula or composition, density, melting point, boiling point, flammability, toxicity, thermal conductivity, stability, reactivity, etc.
Helium is the noble gas in the list provided.
Gas thermometers typically use either nitrogen or helium as the gas inside the thermometer. These gases are preferred due to their low boiling points and well-defined expansion and contraction characteristics with changes in temperature.
No, helium is not a semi-metal. It is a noble gas that exists as a monatomic gas at room temperature and does not exhibit the properties of semi-metals, which are elements that have characteristics of both metals and nonmetals.
The most important characteristics affecting gas chromatography separation are the compound's boiling point, polarity, and molecular weight. Compounds with different boiling points will elute at different times, while polarity affects interactions with the stationary phase. Molecular weight influences the time a compound spends in the gas phase, affecting separation.
A gas has no definite shape or volume, as it takes the shape and volume of its container. Gas particles are in constant, random motion and have weak intermolecular forces. Gases are highly compressible and tend to expand to fill the space available to them.
