    Econ 201 Dr. Popp 10/25/12 Helium Shortage The second element on the periodic table; He‚ also known as helium‚ is a gaseous element that is located somewhere in the sun’s atmosphere and deep underground in some natural gasses (Helium 2012.) Helium can be refined and later stored in tanks to be sold to the market. But where exactly does the helium go after it has been refined? And in what state of matter does Helium sell at the most? It is unknown to many‚ but helium is actually used for more than

    emits an alpha particle it is alpha decay‚ the alpha particle emitted contains two protons and two neutrons which is equivalent to a helium nucleus being released. Alpha decay occurs because there are too many protons‚ which causes excessive repulsion within the nucleus‚ and in an attempt to reduce the repulsion the helium nucleus will be emitted from the atom. The helium nucleus is constantly colliding with the walls of the nucleus and due to its mass and energy it will tunnel out of the nucleus.

    press at all. Helium – an inert‚ odourless‚ monatomic element known to lay people as the substance that makes balloons float and voices squeak when inhaled – could be gone from this planet within a generation. B) Helium itself is not rare; there is actually a plentiful supply of it in the cosmos. In fact‚ 24 per cent of our galaxy’s elemental mass consists of helium‚ which makes it the second most abundant element in our universe. Because of its lightness‚ however‚ most helium vanished from our

    D lines) at 589.0 and 589.6 nm -- any sample that contains sodium (such as table salt) can be easily recognized using this pair of lines. One of the most dramatic triumphs of astrophysical spectroscopy during the 19th century was the discovery of helium. An emission line at 587.6 nm was first observed in the solar corona during the eclipse of August 18‚ 1868‚ although the precise wavelength was difficult to establish at the time (due to the short observation using temporary set-ups of instruments

    Lighter‚ basic and abundant elements like hydrogen and helium were formed during the Big Bang. During Big Bang‚ space expansion cooled the early energy dominated universe and a lot of energy transformed into matter. These basic elements were then able to create the early stars and also the stars of today. Inside of these stars lighter elements fused to release large quantities of energy and in the process of doing that converted hydrogen and helium into heavier elementary particles. Such elements would

    six noble gases that occur naturally are Helium (He)‚ Neon (Ne)‚ Argon (Ar)‚ Krypton (Kr)‚ Xenon (Xe)‚ and the radioactive Radon (Rn). They are all odorless‚ colorless‚ and are unreactive chemically. Noble gases are found in the atmosphere‚ the risk of a human being exposed is by inhaling; if the gases are not contained and release there is a serious risk of suffocation when confined to a small area. The gases are used in lighting and photography; Helium‚ Neon‚ Argon‚ and Krypton are used in gas
