Helium Research Paper

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 a very useful resource and balloons are taking way too much. According to the text, “Helium is also a rare natural resource; the known supply of it on earth is limited.” We could be using it for many other things. According to Should Balloons Be Banned, “It even helps send rockets into space” Helium is a recourse that we need to stop wasting on balloons.

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

Helium is a lighter than air gas. It has a 4.00260 atomic mass while air or oxygen has a 15.9994 atomic mass . According to Jefferson Lab editor Thomas Jefferson National Accelerator Facility “Helium, the second most abundant element in the universe, was discovered on the sun before it was found on the earth.” (2017,[online]). Oxygen is one of the most common gas and every living thing needs it to live. “Oxygen is written as

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 raw material are rare to be found on earth which has rich in helium-3 that is mostly used for electronics, nuclear-fusion research and constructing solar panels.

Tiny molecules comprise our world are called elements, there are different kinds of elements, one is Helium, abbreviated by the symbol He. Note that the first letter is uppercase, and the second lowercase. It was discovered in 1868 when a French astronomer, Pierre Janssen, examined spectral lines from the sun and saw an unfamiliar element. The unknown element was named Helium, after the greek word ‘helios’ meaning sun. Though it was discovered on the sun, it can be found in the ground of the Earth. It forms out of the radioactive decay of metals such as uranium and cleveite, and is plentiful in the soil of Texas.

Gallium. Some of you may know what gallium is, but some of you might not. Gallium is a metal that melts at 30 degrees celsius, or 85 degrees fahrenheit, a little cooler than your body temperature. It also boils at around 4,000 F. Gallium blew up on Youtube because of the ‘Fidget spinner’ craze. Although it is a metal that melts in your hand, it isn’t deadly in very small doses. In fact, Gallium is already in your body!

Atomic Number: 7 Atomic Weight: 14.0067 Melting Point: -346.00°F Boiling Point: -320.44° F Density: 0.0012506 g/cubic cm Elemental State at Room Temperature: Gas Element Classification: Non-metal Introduction Nitrogen was discovered in 1772 by Daniel Rutherford. It is one of the most bountiful elements to exist. Nitrogen gas makes up 79.09% of the earth's atmosphere weighing over 4 trillion tons. It is created from liquefied air by the process known as fractional distillation.

Noble Gas is located in far right column of periodic table and is known for having full valence electron shell. Helium, Neon, Argon, Krypton, Xenon, and Radon are known Noble gases in the periodic table. All of those elements are odorless, colorless in standard condition. Ununoctium is the only synthetic element of Noble Gases. The name Noble Gas came from the translation from German noun Edelgas which implied that it is chemically very inert. Because Noble Gas elements have 8 valence electron and stable without any formation of compound, its first ionization energy is highest out of all the groups in periodic table.

There are countless occupations in the world and many of which require a high level of skill and knowledge. In order to become a professional in any field, someone would have to spend a large amount of time being able to learn the tasks and skills needed for that specific occupation. One specific occupation that requires having the expertise of many skills is a Chemist. A chemist is a scientist who specializes in using extensive research and experiments to improve manufactured products and even create new goods. A chemist is required to obtain a bachelor's degree in the specialized field that they wish to pursue, such as: analytical, physical, and synthetic. There are many tools a chemist must be able to use in their day to day tasks, tools such as a benchtop centrifuge, calorimeters, lasers, and spectrometers. Activities a chemist may have to perform

The precise origin of these 'Fraunhofer lines' as we call them today remained in doubt for many years, until Gustav Kirchhoff, in 1859, announced that the same substance can either produce emission lines or absorption lines. Now scientists had the means to determine the chemical composition of stars through spectroscopy. One of the most dramatic triumph 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 1868 August 18th, although the precise wavelength was difficult to establish at the time. Two months later, Norman Lockyer used a cleaver technique and managed to observe the Solar prominence without waiting for an eclipse. He noted the precise wavelength of this line, and saw that no known terrestrial elements had a line at this wavelength. He concluded this must be a newly discovered element, and called it 'helium'. Helium was discovered on Earth eventually and showed the same 587.6 nm line. Today, we know that helium is the second most abundant element in the Universe. We also know today that the most abundant element is hydrogen. However, this fact was not obvious at

According to the article `' Should Balloons Be Banned ?" , "Helium is needed for medical equipment and scientific experiments ." Helium is limited because it is a rare natural resource . Another quote in the article says "Some Scientists are concerned we are depleting the world's supply too quickly ." Isn't silly to waste such a valuable source

Helium was discovered by some astronomers named, Pierre Janssen and Norman Lockyer. Pierre was studying the suns spectrum when he noticed a yellow line. Later Norman discovered that the line could not be produced by any elements they had known in that time. Noticing that a new element was formed that came from the suns spectrum. [4]
