Helium Essay

helium Helium is champion of the probatory noble gases that are normally utilise. This noble gas is employ for many purposes in the valet de chambre however; it is mostly employ to inflate balloons. The find of this extremely, opportunist gas took many hard steps to be discovered though, it was worth it. Helium was spring identified on the sun, in 1868. While observing a solar eclipse from Guntur in Hyderabad State, British India, Pierre Jansen, a French astronomer, spotted a lustrous yellow parenthood that had a wavelength of 587.49 nanometers from the sun. Jansen originally do an assumption that it was sodium. An English Astronomer, named Norman Lockyer, also made an assumption. He also spotted the glossy yellow line merely he assumed it to be the result of an element that was non present in Earth. some(prenominal) of the astronomers assumptions were incorrect, however they did perform the low step in the discovery of atomic itemise 2. Sir William Ramsey, a Scottish chemist, started experimenting with respective(a) acids on old elements and in March 1895, he managed to discriminate atomic number 2. This was achieved when he treated the mineral cleveite with mineral acids and, when he spy the mixture; he assemble it to be the same one and only(a) he saw in the solar eclipse.

With the results that Ramsey gathered, a British physics, William Crookes, identified the element as atomic number 2. Besides being use to inflate a balloon, atomic number 2 has many, various, vital use. An example of helium being used is in a neon sign. nor-east signs dont on the button contain neon just they also contain new(prenominal) noble gases such as, helium. The sustenance colouring of the helium is bright orange red color, in a neon sign. Helium is also used for, marine ventilating system systems, cooling superconducting magnets, helium dating, offering lift in airships and as a protective gas for different industrial uses. In addition, helium is also becomed when hydrogen fusion occurs deep down the sun. Without helium being produced in the sun, the sun would not produce swinging or stir up resulting in the...If you want to develop a full essay, ordinance it on our website: Orderessay
