Helium Research Paper

There are eight planets in our solar system. The ones closest to the sun, are hotter than the ones that are farther away. Neptune is the farthest planet from our sun, that is in our solar system. Because of this distance, Neptune is the coldest planet in our solar system. Neptune is the 4th largest planet in the Solar System. It is bigger than Mercury, Venus, Earth, and Mars.The

A small helium tank measures about two feet (60 cm) high. Yet it can fill over 50 balloons! How can such a small tank contain enough helium to fill so many balloons?

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.

In the nucleus of an atom there are protons and neutrons the number of protons and neutrons depends on the element and ,if it is an isotope of that element. E.g. carbon 12, carbon 12 has six neutrons six protons and 6 electrons . Electrons are located around the nucleus of the atom. Electrons are in shells, the shell closest to the nucleus is 1 , the one after 2 and so on. Each shell can only hold up to a certain number of electrons . the first can hold up to 2 , the second 8 (2+6) the third up to 18 (2+6+10). The general formula for finding out how many electrons a shell can hold is 2n^2. Electrons have a negative charge , while protons have a positive and neutrons have no charge. A atom has the same number of protons and electrons. An ion is formed when an atom loses or gains a electrons .

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

10. Your friend says that what makes one element distinct from another is the number of electrons about the atomic nucleus. Do you agree wholeheartedly, partially, or not at all? Explain.

Have you ever wondered how the planets got their names? By comparing the characteristics and stories of gods with that of planets, the mystery behind the names of the planets will be unveiled.

Did you know that Jupiter not only has 63 moons and the largest of these moons is bigger than Mercury? Or that the temperature on Jupiter can range from -234 to 43,000 degrees Fahrenheit? Jupiter is a complex and extraordinary planet with many interesting features. It is the fifth planet away from the sun, has a noticeable red spot and a strong magnetic field. This planet also happens to be one of the five planets in the solar system labeled a gas giant. Along with Pluto, Uranus, Neptune, and Saturn and is composed mostly of gases. Jupiter is specifically made up of hydrogen and helium. One of the largest in the solar system, is composed of many different layers, and turns on its axis quicker causing shorter days.

It is 78% nitrogen and 21% oxygen with trace concentrations of water vapor, carbon dioxide, and other gaseous molecules. Jupiter’s atmosphere is composed primarily of hydrogen and helium, with trace amounts of other elements.

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 in the atmosphere, but is used for tons of different jobs and situations.

The Rings of Saturn make Saturn unique. Unlike other planets with only a few rings, Saturn has thousands of colorful rings are made of mostly rock and ice. The rings stretch 282,000 kilometers across but are only 100 meters (0.1 km in comparison) high at

Gallium is the element number 31. Gallium is the one of the only metal that will be liquid in your hand. Mercury is an liquid metal element number 80 that freezes at -280 degrees fairenheight with liquid nitrogen. Mercury was a popular thing to play with but people realized that they were slowly being poisoned by it.Gallium is not known to be toxic, but it can stain your hand dark brown. cesium is another metal that will literally melt in your hand but without putting it in an ampoule, it will explode and catch on fire. Gallium tends to be the less dangerous type of liquid metal other than explosive cesium to lethal mercury. Gallium melts at a temperatue of 83.4 fairenheight. In order to buy gallium you must first order it then, they must purize

White petrolatum is associated with fewer instances of hypersensitivity reactions and is the preferred petrolatum for use in cosmetics and topical pharmaceuticals. White petrolatum has been tentatively implicated in lipoid pneumonia following excessive use in the perinasal area. Other adverse reactions to petrolatum include granulomas (paraffinomas) following injection into soft tissue (86). Also, when taken orally, petrolatum acts as a mild laxative and may inhibit the absorption of lipids and lipid-soluble nutrients.

Helium in the ancient days was a name use for the Greek god of the sun, Helios until three different scientist came across it in the nineteen hundreds. We find helium in blimps, birthday balloons, we also find helium in the earth’s atmosphere. Helium is also used in chemistry like scientific balloons, to insert shield in arc welding, and to pressurize the fuel tanks of liquid fueled rockets in supersonic wind tunnels, and for certain things in the laboratory.

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 with your lungs part of the time. Helium has physical and chemical properties, economic importance, industrial uses, with a decrease in quantity and future advantages.
