Helium

Helium (Greek helios,"sun"), symbol He, inert, colorless, odorless gas element. In group 18 of the periodic table, helium is one of the noble gases. The atomic number of helium is 2. Pierre Janssen discovered helium in the spectrum of the corona of the sun during an eclipse in 1868. Shortly after it was identified as an element and named by the chemist Sir Edward Frankland and the British astronomer Sir Joseph Norman Lockyer. The gas was first isolated from terrestrial sources in 1895

Helium and How It Impacts This World The origin of the second element on our periodic table still hasn’t fully been found, neither the many secrets that it holds. Helium is one of first know elements to every been discovered, and still is being examined and studied for any other hidden secrets that it might hold. While some people might believe that it’s a element that is hardly used, it would shock people to discover that as human beings, helium is a daily element that surrounds us not only just

Helium is the first noble gas on the Periodic Table. The symbol of Helium is “He”, and the Atomic number is 2. This element has a atomic mass of 4.00g. Helium was first discovered on the sun as a cooler gas by Sir William Ramsay. The noble gas helium was given it’s name referring to the Greek goddess “Helios”,on August 18, 1868. Helium is the second top element on planet Earth. Also, it is the gas that scientist found that was leaking from Mt. Vesuvius in Italy. The Gas that can give a weird reaction

Helium is a colorless, tasteless, and odorless gas. It has some very unique properties. Helium has the lowest boiling point of all the elements at -268.9C, or -452.0F. Its freezing point is -272.2C, or -458.0F. Helium is the only gas that can not be turned to a solid by lowering its temperature. To make helium solid you have to increase its temperature. When helium is at a temperature of -271C, it is a liquid but it has superfluidity properties. This means that liquid helium flows it doesn’t exert

Although Helium exists in the atmosphere of Earth in small quantities, it is one of the most common element in the universe. It is a rare gas on earth. Helium was first discovered by Pierre Janssen in the spectrum of the sun during an eclipse in 1868. It was shortly identified as an element and was named by the chemist Sir Edward Frankland and the British astronomer Sir Joseph Norman Lockyer. Helium has an atomic number of 2 and an atomic weight of 4.002602. Helium is represented by the symbol

Helium makes up about Helium is the second most abundant element in the universe. It was discovered on the sun before it was found on earth. In 1868 a french astronomer, Pierre-Jules-Cesar Janssen noticed a yellow line in the sun’s spectrum while studying a total solar eclipse. With a wavelength of 587.49 nanometers Norman Lockyer realized that this line could not be produced by any element at the time. It was hypothesized that the sun was responsible for this mysterious yellow emission. Lockyer

are fluids that have zero viscosity. This means that the fluid will flow with zero friction as well as leak through certain surfaces that are otherwise considered sealed. In addition, superfluids are also superconductors. The paper discusses liquid helium, its discovery, properties applications and limitations. INTRODUCTION The discovery of what are known as “superfluids” was made relatively simultaneously in 1937 by two independent factions on opposite sides of the world. One was Pyotr Kapitsa in

Today, about 70% of the earth is covered with water, and that is because of the evolution of the ocean system. Before that happened however, our solar system was created. One of the persisting theories when it comes to the creation of our solar system is the Big Bang Theory. This theory basically states that “12 to 14 billion years ago, the portion of the universe we can see today was only a few millimeters across. It has since expanded from this hot dense state into the vast and much cooler cosmos

on the mass of the star, they can reach different types of fusion. Normal stars that have a mass of up to 4 times the sun can only have hydrogen fusion, helium fusion, and carbon fission. Stars with a bigger mass is classified as a massive star, and they undergo multiple stages. They start out similar to the normal stars with hydrogen fusion, helium fusion and carbon fission, but continue over to oxygen fusion, and silicon fusion. The end product of Silicon is Iron. No star can fuse Iron, it will die

If a Wisconsin Fast Plant has sunlight, water, but not fertile soil, it’s helpless. If a star has helium but not hydrogen, it’s dead. In which a similar similarity is that both do not ask for much to live: stars would like space to breathe and grow, hydrogen, and helium. Wisconsin Fast Plants would like water, sunlight, fertile soil, and room. That too brings up another similarity topic: death rate. With both stars and Wisconsin Fast
