What is the major source of helium that is used on earth?
143420
The helium from most of the alpha particles, however, has been trapped deep within the earth, not far from the top of the mantle. Helium diffuses very rapidly, so it can be expected to have been mobile in the crust. The Great Plains of the United States consist of a thin crust of sedimentary rock on a basement of igneous rock that would be a source of radiogenic helium. The helium has collected where other gases have collected, depending on the chances of distribution. In some of these gases, helium is present up to about 8% by volume, a surprising amount. However, in most gases the abundance is less than 1%, sometimes much less, and the occurrence is very rare on a world-wide basis. Some natural gas or well helium, as radiogenic helium from the earth is also called, is found in the Canadian west, and, in lesser quantities, in gas associated with the blue rock salt of Germany, and a few other locations. There may also be helium in Siberia, where the geologic conditions resemble those of the Great Plains.\n\nPorous and permeable rocks deep below the surface are often saturated with salt water, at a pressure of the same order as the hydrostatic pressure at that depth, called the formation pressure. Since 33 ft of water corresponds to 1 atm, or 14.7 psi, the formation pressure at 3300 ft would already be 1470 psi. Gases in permeable rocks collect at the highest points they can reach, and there form a "cap" of gas, possibly underlaid with liquid petroleum. A well drilled into the part of the formation containing liquid petroleum would soon fill with the liquid and flow out of the hole, as quickly as it could ooze into the hole. The weight of the petroleum would largely balance the formation pressure, so the oil would generally flow placidly. In rare cases, the formation pressure might be high enough to project a jet into the air, a "gusher." As formation pressure is lost, as it always is when holes are drilled, the oil might not reach the surface, and then it would have to be pumped out mechanically. Oil cannot be sucked from rocks; you can only collect what shows up.\n\nWith gas, what happens is quite different. The gas is so light that it cannot balance the formation pressure, and the gas exits from the hole at high pressure, unless confined (perhaps by the fluids used in drilling the well). Such a well was called a "blower" in early days, and the owners hardly realized that what was blowing out was, in effect, their wealth, since with depleted formation pressure little oil or gas could be produced. A gas well is exhausted when the pressure is no longer sufficient to bring the gas to the surface at sufficient pressure. These days, much gas in the western United States is produced from shallow coal-bed wells or from formations of small permeability, or "tight" formations. This gas has to be compressed before it can be put into the gas pipeline.\n\nNatural gas is often thought of as methane, CH4, and most marketable natural gas is chiefly methane. However, the gas ranges from a rich gas containing considerable ethylene and even heavier components, which give it a high heating value, down to lean gases containg so much nitrogen that it will not even burn if ignited. The bacteria that produced the oil also leave behind carbon dioxide and hydrogen sulphide, which are often found in the gas. Hydrogen sulphide makes the gas poisonous and of foul odor; such gas is called "sour." The hydrogen sulphide is relatively easily removed, and the sulphur that results is a valuable by-product. Some gas is almost pure carbon dioxide, and many wells are produced for the carbon dioxide, a valuable chemical. Indeed, carbon dioxide is often pumped underground to repressurize a formation, and serve as a lubricant for getting the oil out. Sweet natural gas has little odor and is not poisonous.\n\nSome of this natural gas also contains helium. Gas rich in helium usually also has considerable nitrogen, but

Helium is a colorless, odorless, tasteless chemical element. It is the most unreactive of the noble gases and therefore the least chemically-active chemical element on the periodic table. Its boiling and melting points are the lowest among the elements; except in extreme conditions, it exists only as a gas. At temperatures near absolute zero, it is a superfluid, a nearly frictionless phase of matter with unusual properties.\n\nAfter hydrogen, helium is the second lightest element and the second most abundant element in the universe, created during big bang nucleosynthesis and to a lesser extent from nuclear fusion of hydrogen in stars. On Earth, helium is primarily a product of the radioactive decay of much heavier elements, which emit helium nuclei called alpha particles; it is found in significant amounts only in natural gas, from which it is extracted at low temperatures by fractional distillation.\n\nFirst detected in 1868 by French astronomer Pierre Janssen as an unknown yellow spectral line signature in the light of a solar eclipse, helium was separately identified as a new element later that year by English astronomer Norman Lockyer. Its presence in natural gas in large, useable amounts was identified in 1905. Helium is used in cryogenics, as a deep-sea breathing gas, for inflating balloons and airships, and as a protective gas for many industrial purposes, such as arc welding. Inhaling a small amount of the gas temporarily changes the quality of a person's voice; however, caution must be exercised as helium is an asphyxiant.\n\nHelium is a colorless, odorless, and non-toxic gas. It is the least reactive member of group 18 (the noble gases) of the periodic table and therefore also the least reactive of all elements; it is inert and monatomic in virtually all conditions. It has a thermal conductivity that is greater than any gas except hydrogen and is specific heat is unusually high. Helium is also less water soluble than any other gas known and its diffusion rate through solids is three times that of air and around 65% that of hydrogen.[1] Helium's index of refraction is closer to unity than any other gas. Helium has a negative Joule-Thomson coefficient at normal ambient temperatures, meaning it heats up when allowed to freely expand. Only below its Joule-Thomson inversion temperature (of about 40 K at 1 atmosphere) does it cool upon free expansion. Once precooled below this temperature, helium can be liquefied through expansion cooling.\n\nHelium is chemically unreactive under all normal conditions due to its valence of zero. It is an electrical insulator unless ionized. As with the other noble gases, helium has metastable energy levels that allow it to remain ionized in an electrical discharge with a voltage below its ionization potential. Helium can form unstable compounds with tungsten, iodine, fluorine, sulfur and phosphorus when it is subjected to an electric glow discharge, through electron bombardment or is otherwise a plasma. HeNe, HgHe10, WHe2 and the molecular ions He2+, He2++, HeH+, and HeD+ have been created this way. This technique has also allowed the production of the neutral molecule He2, which has a large number of band systems, and HgHe, which is apparently only held together by polarization forces.[1] Theoretically, other compounds, like helium fluorohydride (HHeF), may also be possible.\n\nThroughout the universe, helium is found mostly in a plasma state whose properties are quite different to molecular helium. As a plasma, helium's electrons and protons are not bound together, resulting in very high electrical conductivity, even when the gas is only partially ionized. The charged particles are highly influenced by magnetic and electric fields. For example, in the solar wind together with ionized hydrogen, they interact with the Earth's magnetosphere giving rise to Birkeland currents and the aurora.\n\n\n[edit] Solid and liquid phases\nHelium solidifies only under great pressure.

maybe you would want to measure the helium content on moon and compare it to earth.

Yes.  There is a very small amount of matter that enters the atmosphere from space (meteorites), but essentially it is all just being recycled. Some atoms of oxygen you breathe in may have been breathed by a dinosaur, or one of the pharoahs!

It depends on if you are looking at large quanities or just any ammount goes. It also depends on if you are looking at elements that are only found in compounds or not. Oxygen, hydrogen, argon, carbon, nitrogen, alluminium, silicon, iron, tugstan, lithium, potassum, titanium to name a few. almost all of the elements can be found near the earth's surface except those that are man made, usually the extremly heavy ones like plutonium.

Helium bomb? Do you mean hydrogen bomb?\n\nAnyway, an atomic bomb uses uranium or plutonium, heavy elements, and bombards them with a force, which splits the heavy nuclei into smaller nuclei, with a huge rush of energy. This is called nuclear fission.\n\nHydrogen bombs are kind of the opposite. They perform nuclear fusion, which is much harder to do. Hydrogen bombs use atomic bombs to provide the force. In the center is a pellet of deuterium, a hydrogen isotope with a neutron. The deuterium fuses together to form helium, creating a much, much, much bigger explosion than fission.\n\nOne modern hydrogen bomb can instantly vaporize all the water in the San Francisco Bay.

Lighter elements (like hydrogen and helium) have been present since the beginning of time, and we see them largely in stars undergoing fission and fusion processes.  It is THESE processes (combustion of hydrogen and helium in a star) that CREATE heavier elements.\n\nThis process takes time.  We can only get elements up through iron before we need suns to take over and start crafting heavier ones.  That is why we see predominantly helium and hydrogen... it takes a while to make the rest.

That depends on what you mean; Carbon is found in its pure form as graphite (pensil lead) and diamond.  It is a major component of coal, and a fairly large amount of every living organism on the planet.  For experiments using carbon (like production on nanotubes), pure carbon monoxide gas is typically used in a high-energy environment (like high power lasers, plasma gas, etc).  The carbon dioxide (CO) is produced from iron pentacarbonyl (Fe(CO)5).

When the person speaks, the helium in his lungs go into his mouth and out of his mouth and into the immediate space in front of it.\n\nWhen you hear his voice, it will have gone through a substantial amount of helium before going through air :)

They are isotopes. Different isotopes of the same element can exist and these are caused by differing number of neutrons.\n\nThe "common" isotope of Helium is Helium-4 (it has 2 protons and 2 neutrons, hence the 4). \n\nHelium-3 is a variety of Helium (far less common than Helium-4) which has two protons but only one neutron.

No. Combustion occurs b/c something reacts with oxygen. So unless the helium is contaminated with oxygen, no combustion can take place.

Under high pressure, the helium is liquified.  The tank is then attached to the pressurized tank and helium simply pours into the tank via gravity.  When the tank is opened, atmospheric pressure converts it back to gas.

In the context of your question,\n\nA resource is a source of material or energy that may be consumed, changed, or dispersed to the point it is no longer easily usable. Examples would be copper ore, oxygen in the atmosphere, helium gas taken from oil wells, water, sand, or even soil. Anything we do consumes or utilizes some sort of resource. Breathing uses oxygen from the air. Copper is used for wiring and piping. Helium is used for scientific research and birthday balloons. Sand is used to make concrete. Water is used for drinking, irrigation, and generating hydroelectric power. Soil is used for growing crops.  None of these are exhaustive lists, just examples. \n\nOil: Oil is a mixture of organic compounds extracted from the earth by drilling. It is created from organic materials deposited in sedimentary rock that are altered by heat, pressure, and biotic processes to create it. \nOil is used to make gasoline, diesel, airplane fuel, plastic, shampoo, rubber, antihistamines, and many other products. \n\nNatural gas: It is an organic gas that is also extracted from the earth by drilling. It is generated by a similar process to that for oil generation. It is used to heat homes, make fertilizer, and some plastics. \n\nWater: Water is found in many forms, but mostly as either fresh or saltwater. Fresh water is used for drinking, irrigation, etc. Saltwater is not as useful directly to man, but is an essential part of our environment as the oceans both support food supplies and have a large effect on the climate. \n\nWood: Wood comes from living organisms- trees. Wood can be used for building many things, including houses. It is used for fuel and is the primary source of fuel in some parts of the world.

What is air?  It is a mixture of gases, trapped in the gravity of the Earth, that form an envelope around our planet.  It is a mixture of nitrogen (~78%), oxygen (~21%), and the rest small amounts of carbon dioxide, water vapor, argon, neon, carbon monoxide, and traces of other gases.\n\nIf there were no nuclei present, there would be no matter present, and that is the definition of a vacuum.

It has been stated that the sun has a great deal of hydrogen within it due to the necessity of it being converted into helium, and the energy difference generating its heat potential.  There is a problem with this concept.  Although there is energy release in the conversion of hydrogen to helium, the interior of our sun is not what has been taught in your school.\n\nWere you to determine the acceleration value of a mass 400 miles from the very center of our sun, you would find that were a mass to be released in this location, it would accelerate to a speed greater than that of light in one second.  This means there is not a continual atomic furnace generating heat by the process of hydrogen to helium as taught.  Either there is a hollow area within our sun where mass cannot exist, or there is a new form of mass unknown to mankind.  Offhand I would reject the last.\n\nThe reason helium and/or oxygen could not burn within our sun is that the pressure surrounding the gases is too great.  Notice when you burn a piece of paper how the smoke spreads outward along with the heat energy.  Within the sun the heat energy is already beyond that of what we would experience on our planet.  There is nothing to change.

Helium is a gas that is ONLY found trapped inside rocks ( on Earth ).\n\nThis is because Helium is so light that it will escaped into SPACE when released.  ( Helium is not found in the air )\n\nYour helium balloon will explode before it stops rising.\n\nIf the balloon doesnt explode ( for example only ) , then it will rise into space and stabilize in a orbit at an equilibrium point where the gravitational attraction of the Earth to the substance of the balloon matches the lift of the balloon ( the tendency of Helium to escape ).\n\nI dont know where this point would be but i dont think its necessary to understand your question.
