Where can helium be found? Confidence votes 5.0K. Helium can be found in underground deposits in the earth. Helium can also be found in stars and other planets. +++. The helium underground-and extracted from natural-gas-is a by-product of the natural radioactive decay of uranium, though is far too stable to be radioactive itself. It also occurs in very small amounts in the atmosphere.

- Because it is very unreactive, helium is used to provide an inert protective atmosphere for making fibre optics and semiconductors, and for arc welding. Helium is also used to detect leaks, such as in car air-conditioning systems, and because it diffuses quickly it is used to inflate car airbags after impact. A mixture of 80% helium and 20% oxygen is used as an artificial atmosphere for deep-sea divers and others working under pressurised conditions. Helium-neon gas lasers are used to scan barcodes in supermarket checkouts.

Helium Helium is commercially available in either liquid or gaseous form. As a liquid, it can be supplied in small insulated containers called dewars which hold up to 1,000 liters of helium, or in large ISO containers which have nominal capacities as large as 42 m 3 (around 11,000 U.S. gallons).

Helium In 1905, natural gas taken from a well near Dexter, Kansas, was found to contain as much as 2% helium. Tests of other natural gas sources around the world yielded widely varying concentrations of helium, with the highest concentrations being found in the United States.

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.

Uses of Helium 1 It is used in the field because of its low boiling point and low density. 2  It is mainly used to cool superconducting magnets in MRI scanners. 3  Helium is also commonly used to pressurize and purge systems of unwanted gases.

HELIUM Helium is a colorless, odorless, tasteless gas. It has a number of unusual properties. For example, it has the lowest boiling point of any element, -268.9°C (-452.0°F). The boiling point for a gas is the temperature at which the gas changes to a liquid.The freezing point of helium is -272.2°C (-458.0°F).elium is a member of the noble gas family. The noble gases are the elements in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how the elements are related to one another. The noble gases are also called the inert gases.

Helium in Your Daily Life Helium in Your Daily Life. Helium is known as He on the periodic table. Helium is the second most abundant element in the universe and was discovered on the sun before it was found on the earth. It has been detected in great abundance in hotter stars and it is an important component in both the proton-proton reaction and the carbon cycle, which accounts for the energy of the sun and stars.

HE-LI-UM Even when first discovered and identified, scientists knew there were large amounts of helium in the Sun. Similar to hydrogen (H), helium is usually found as a gas and has no color or smell. Helium is found everywhere in the Universe and is the second most common element, just behind hydrogen. As far as we're concerned, helium is a happy element.

Helium: the essentials Helium around us. Helium has no biological role. Helium is present in the atmosphere at about 0.0005% (1 part in 200000) by volume and is an important component within hydrocarbon gases in the USA. Its origin in these gases is traced to the decay of radioactive elements in rocks.

CHAPTER 6 Overhead fire is fire delivered over the heads of friendly troops. A machine gun on a tripod is capable of delivering this type of fire because of the small and uniform dispersion of the cone of fire. In the attack, the use of overhead fire permits the machine gun to support the advance of rifle units.

Noble gas The abundances of the noble gases decrease as their atomic numbers increase. Helium is the most plentiful element in the universe except hydrogen. All the noble gases are present in Earth’s atmosphere and, except for helium and radon, their major commercial source is the air, from which they are obtained by liquefaction and fractional distillation.

Helium Helium is named for the Greek god of the Sun, Helios. It was first detected as an unknown yellow spectral line signature in sunlight during a solar eclipse in 1868 by French astronomer Jules Janssen. Janssen is jointly credited with detecting the element along with Norman Lockyer.

Alpha decay Approximately 99% of the helium produced on Earth is the result of the alpha decay of underground deposits of minerals containing uranium or thorium. The helium is brought to the surface as a byproduct of natural gas production.

Helium Element Facts Cost, bulk: $ per 100g. Source: Nearly all the helium on Earth is the result of radioactive decay. The major sources of helium are from natural gas deposits in wells in Texas, Oklahoma and Kansas. Helium is extracted by fractional distillation of the natural gas, which contains up to 7% helium. Isotopes: Helium has 8 isotopes whose half-lives are known, with mass numbers 3 to 10.

Helium: A byproduct of the natural gas industry Helium has a very low viscosity, a high diffusion coefficient, and the smallest atom of any element. These characteristics make helium very hard to contain. If a system has a leak, helium will escape. Helium gas is therefore used to test high vacuum systems, fuel systems and other containments for leaks.

- Noun. 1. helium-a very light colorless element that is one of the six inert gasses; the most difficult gas to liquefy; occurs in economically extractable amounts in certain natural gases (as those found in Texas and Kansas).

Where is neon commonly found? Confidence votes 14.2K. Neon is a gas found in the air. When air is cooled to the point where nitrogen becomes liquid, other gasses such as oxygen, argon, and neon, also become liquid. So neon is produced in as a byproduct of making liquid nitrogen for cooling and oxygen for the oxygen reduction process of making steel.

- Hydrogen is easily the most abundant element in the universe. It is found in the sun and most of the stars, and the planet Jupiter is composed mostly of hydrogen. On Earth, hydrogen is found in the greatest quantities as water. It is present as a gas in the atmosphere only in tiny amounts – less than 1 part per million by volume. Any hydrogen that does enter the atmosphere quickly escapes the Earth’s gravity into outer space.

- 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.n Earth it is relatively rare — 5.2 ppm by volume in the atmosphere. Most terrestrial helium present today is created by the natural radioactive decay of heavy radioactive elements (thorium and uranium, although there are other examples), as the alpha particles emitted by such decays consist of helium-4 nuclei.
