Because it remains a gas at very low temperatures, it can be used as a purging gas
Helium gas is used to inflate blimps, scientific balloons and party balloons. See G. A. Cook, Argon, Helium and the Rare Gases (2 vol., 1961); I. Asimov, The Noble Gases (1966). Helium shows up in semiconductors, birthday balloons and the Large Hadron Collider. thorium in.Helium has the smallest atomic radius of any element, about 0.2 nanometers. In the first auction, two
Helium definition, an inert, gaseous element present in the sun's atmosphere and in natural gas, and also occurring as a radioactive decomposition product, used as a substitute for flammable gases in dirigible balloons. metals from oxidation and other reactions that might occur rapidly at high temperatures.Helium is a gas that is only found where a coincidence of unlikely

Helium is used here because it is inert, has a very low viscosity and is easier to breathe under pressure
An inert gas is a gas that does not usually react chemically with other things. According to the.Earth's atmosphere is only about 5 parts per million, or 0.0005 percent, helium. The only gas with a lower reactivity is neon. It is lighter than air.Most people know that helium is used as a lifting gas in blimps and party balloons, but they can't name another way in
Inhaling helium is dangerous because it can cause your body’s oxygen level to drop to dangerous low levels, initiating Hypoxia. 'Sun') is a chemical element with the symbol He and atomic number 2.
