It's Elemental Helium is commercially recovered from natural gas deposits, mostly from Texas, Oklahoma and Kansas. Helium gas is used to inflate blimps, scientific balloons and party balloons. It is used as an inert shield for arc welding, to pressurize the fuel tanks of liquid fueled rockets and in supersonic windtunnels.

- Gaseous helium is used for gas metal arc welding and gas tungsten arc welding. The helium serves mainly as a shielding gas, preventing atmospheric contamination of the molten metal and stabilizing the arc.

Uses of Helium Helium is an inert noble gas with the chemical symbol He and the atomic number 2. Its boiling and melting points are the lowest of any known element. Helium is both the second lightest and second most abundant element in the universe. Helium exists naturally in a gaseous state and is colorless, odorless and tasteless.

Helium Helium's other industrial uses—as a pressurizing and purge gas, as a protective atmosphere for arc welding and in processes such as growing crystals to make silicon wafers—account for half of the gas produced. A well-known but minor use is as a lifting gas in balloons and airships.

FREQUENTLY ASKED QUESTIONS All balloons are porous and this means that the helium will eventually escape from them. Latex balloons are the most porous and because of this they let the helium escape much quicker than bubbles and foil balloons.

HELIUM Helium is a good gas to use for this purpose because it does not react with anything in the pipe. Helium is also used to inflate balloons and other lighter-thanair crafts, such as dirigibles (blimps). Helium does not have the lifting power of hydrogen. However, hydrogen is flammable and helium is not.

Helium In gaseous form, small quantities of helium are supplied in high-pressure cylinders holding as much as 8 m 3 (approx. 282 standard cubic feet), while large quantities of high-pressure gas are supplied in tube trailers which have capacities of as much as 4,860 m 3 (approx. 172,000 standard cubic feet).

Why Is There a Helium Shortage? One of the most abundant elements in the universe is getting harder to come by. Helium goes into a lot more than balloons. Because the gas is inert and has extreme melting and boiling points—both near absolute zero—scientists use it in cryogenics, high-energy accelerators, arc welding, and silicon wafer manufacturing.

- Helium is a chemical element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas that heads the noble gas group in the periodic table. Its boiling and melting points are the lowest among all the elements.he speed of sound in helium is nearly three times the speed of sound in air. Because the fundamental frequency of a gas-filled cavity is proportional to the speed of sound in the gas, when helium is inhaled there is a corresponding increase in the resonant frequencies of the vocal tract.

Is Helium Gas Used to Fill a Balloon a Substance or a Mixture? Is helium gas used to fill a balloon a substance or a mixture? A: Most of the helium gas used to fill balloons is a mixture because commercial helium is seldom pure. Usually, it contains impurities in the form of nitrogen and oxygen gas. However, the helium present in this mixture is also a substance. Continue Reading.
