Helium Research Papers

This can make these elements every dangerous because some are toxic to humans and animal if they inhale them. It is hard to detect when these elements are in the air around you in dangerous amounts without proper equipment. Due to their state of being, and the fact that some are toxic they need to be handled properly by a professional to insure that no harm comes to those in the surrounding environment. The fact that all of the elements in the Noble Gases group are gases make them unique because other elemental groups have an array of different states of matter in their element groups.

Based on this, what can you infer about the reactivity of helium and neon? They are both noble gases so they are very resistant to a chemical reaction and don’t react to other elements.

Helium is the second most abundant element in the universe, after hydrogen; however, it is rare on earth, primarily found mixed with natural gas trapped in underground pockets. Once helium is released it is so light it escapes the earth's atmosphere and cannot be recovered. At sea level, helium occurs in the atmosphere in the proportion of 5.4 parts per million. The proportion increases slightly at higher altitudes. About 1 part per million of atmospheric helium consists of helium-3, now thought to be a product of the decay of tritium, a radioactive hydrogen isotope of mass 3. The common helium isotope, helium-4, probably comes from radioactive alpha emitters in rocks. Natural gas, which contains an average of 0.4 percent helium, is the major commercial source of helium. By far the largest users of helium are agencies of the United States government.

Helium is rare because there are no biosynthetic ways of making it, and all the helium that we currently have in the world is a result of the decaying uranium and thorium

 This planet’s atmosphere is mostly hydrogen, with 15% helium and a little bit of

Hydrogen is like the “mother” to all elements because it was fused together to create new ones such as helium which then fused together to create and lithium. My next favorite element is helium. The element stood as an interesting to point to me since I learned that it was an abnormal noble gas in Chemistry in 10th grade. In Chapter One of The Disappearing Spoon, Kean discussed the use of helium as a superconductor at temperatures below -450 degrees Fahrenheit. From my physics class, I knew that superconductors were things that had no resistance and conducted electricity the best.

The noble gases are the gaseous elements helium, neon, argon, krypton, xenon, and radon, in group 18 of the periodic table. Additionally, they are considered the most unreactive of the elements, due to the fact that the valence electrons are all “full”, thus making the group the most stable, as well. When it comes to the periodic trends, the noble gases have the some of the lowest densities because they are gaseous elements, meaning they state of matter consisting of particles that have neither a definite volume nor definite shape. The lack of electronegativity of the noble gasses is based off of their group, which already has a full outer shell, meaning they do not attract any electrons.

Helium is the coolest thing in the world. It changes your voice. It makes your voice higher when your voice is really low. You put it in Balloons to make it stay up. You usually use it for party's. Well the first time that I did it it was really funny. But for my grandpas surprise birthday party we used helium for the balloons.

The discovery of such an element as gallium does not come as just any accidental discovery. Gallium or Ga, atomic number 31 was in a long research process for fifteen years by Lecoq de Boisbaudran. He had been meticulously studying the spectra of several chemical elements, Lecoq knew that each and every element produces its very own and distinct pattern of lines when heated, or spectra. As Lecoq de Boisbaudran continued his drive to learn more of the distinct element spectra, he distinguished that the element on the periodic table between indium and aluminum was yet to be discovered.

Helium is the second most abundant element in the universe, but there is a shortage on earth.In one of the main helium reservoirs in the U.S. there was only 10 - 12 billion cubic feet of helium left in it, as of 2012. Even though this seems like a lot, we use around 2 billion cubic feet of helium per year. So technically that reservoir would be getting very very close to

Neon is number ten on the periodic table and the second element in Group 18. As previously stated it was named after the Greek word, neos, meaning new ("Neon," 2008). It is part of the noble gases family and its chemical symbol is Ne. With an atomic mass of 20.1797 it is a nonmetal ("Neon," 2000). Also, At room temperature it is a gas (Jefferson, n.d.). Being a noble gas it is odorless, colorless, tasteless and chemically inert. It’s boiling point is -410.94°F (-246.08°C), it’s freezing point is -415.46°F (-248.599.002°C), and it has a density of 5.202 x 10-4 ounces per cubic inch. No compound has ever been made with

Gallium has some incredibly versatile uses. As mentioned, gallium has a very low melting point, but an incredibly high boiling point which makes it useful for high-temperature thermometers. Very high temperatures would vaporize a regular thermometer, due to their boiling points being much lower than gallium’s. Since gallium can form alloys with other metals quite easily, it can be used to form alloys that have low melting points. Gallium arsenide makes a useful silicon substitute in the electronics industry. It can be used as a doping material for semiconductors. Gallium arsenide can also produce laser light directly from electricity. In addition, gallium can be used to produce items such as transistors and light emitting diodes. However, gallium has no known biological role.

The element neon is a nonmetal. When at lab temperature, neon is a gas. When at freezing point, neon turns from a liquid to a solid. When at condensing point, neon turns from a

Atmosphere of neptune has similarities to all the large planets in the solar system, but unlike the other gas planets in the solar system, its atmosphere has a bigger proportion of ices. The surface of neptune is one of the coldest planets in the solar system. At its surface the clouds of the planet touch space. The temperature of Neptune can dip down to -210 degrees C.
