Helium

Sir William Ramsay and Morris Travers founded neon in 1898, by experimenting on liquid air. Prior to discovering neon they had recently found krypton, then later on they would go to discover xenon. “ Ramsay knew that sometimes one element could stay hidden behind another element (Stewart www.chemicool.com/elements/neon.html).” Neon was actually named by Ramsay’s son and was named neon after greek words neos (which means new). After Ramsay and Travers were able to keep finding neon it opened…

Do you know exactly what the element Argon is? Argon is a colorless, odorless, chemically inactive, monatomic, gaseous element that, because of its inertness, is used for filling fluorescent and incandescent lamps and vacuum tubes. In this paper you will be educated about when Argon was discovered, where it can be found on the Periodic Table, some of its properties, and some of the uses for Argon. Argon was discovered in 1894 by two chemists. The two chemists were Sir William Ramsay, who was a…

The Sun is far from fully understood and today the two biggest questions related to the Sun is the reason for the high temperature in the corona and how to explain the sunspot cycle \cite{PB}.

Neon was discovered in the late nineteenth century. In the 1890s, John William Strutt observed that nitrogen extracted from the air was always slightly heavier than nitrogen obtained from chemical compounds. This curiosity was noted previously by Henry Cavendish, but it remained anonymous. ("Neon," 1999). In 1898, a Scottish chemist Sir William Ramsay (1852-1916) and English chemist Morris M. Travers (1872-1961) discovered neon just after they discovered the element krypton that same year.…

Helium is the second element in the periodic table. Its period number is 1 and it is apart of group number: 18. The group that Helium falls under is the Noble Gases. The element has an atomic number of 2, an atomic mass of 4 and is classified as a non-metal. It is the second most abundant element in the universe. Helium was discovered on the sun before it was found on the earth. In 1895, Pierre-Jules-César Janssen, a French astronomer and Norman Lockyer, an English astronomer both who discovered…

Even though helium (He) is the second most abundant element in the universe, it is the most important element. First, let me provide you with some information about helium and its history Helium was first discovered in the sun and not the earth. In 1868, astronomer Pierre Janssen found this gas while watching the colors when the sun was going thru a full solar eclipse. Since the Greek word for sun is helios, he named the gas helium. It was not until 1895 that helium was discovered on earth…

Superfluid helium or He II is a macroscopic quantum fluid that exhibits extraordinary properties. %By applying the limit of low flow velocities, The behavior of the fluid can be understood using a Landau - Tisza model, where He II is considered to be a two-component fluid with independent velocity fields: the inviscid superfluid of density $\rho_s$, and the normal fluid of density $\rho_n$, where the total density $\rho$ = $\rho_s$ + $\rho_n$ \cite{Tisza,Landau}. The superfluid has neither…

These elements, from smallest to greatest atomic mass, are Helium, Neon, Argon, Krypton, Xenon, and Radon. Group 18 wasn't always called the noble gases. this group used to be called the inert gassses. They changed the name of thisi group because they are not always inert, or chemically inactive. the first element in this group is the element Helium. Helium has an atomic number of 2, and the chemical symbol for helium is He. helium is in the first period. The second element in this group…

not help in anyway. They kill our wildlife, they use our helium which we only have so much of, and they can catch on fire! Wow, all of those bad things just we can have a balloon at our birthday party? Nope I don’t think so! The biggest reason I am against balloons is because they kill our wild life! According to Romero “When we let them go it could harm wildlife” page 24 line 22,23. People love to get balloons that are filled with helium which make them float, and they like to…

was not there then Earth and all of its environments would not be able to survive. The sun is mostly hydrogen and produces energy through nuclear reactions. The reactions are specifically nuclear fusions. This is because of hydrogen atoms becoming helium atoms. Heat, Light, and the Sun It always feels good to go outside when there is just the right amount of breeze and sunshine. The breeze and sunshine together make up the right temperature. The breeze adds a little cool down to match the…
