Helium: The Unknown Element

Elements are substances that cannot be separated into smaller substances and are made up entirely of one type of atom. Naturally existing elements can be categorized as either light elements or heavy elements. During the Big Bang light elements were formed such as hydrogen, lithium, lithium and deuterium. The heavy elements originated from Stellar Nucleosynthesis. Heavy elements, however, are formed such as uranium and iron are formed through Stellar Nucleosynthesis while materials heavier than this are formed through a supernova.

The most common elements on earth are hydrogen, and helium that mostly formed after the big bang.

The identity of each element is defined by the number of protons in its nucleus

The second element on the periodic table; He, also known as helium, is a gaseous element that is located somewhere in the sun’s atmosphere and deep underground in some natural gasses (Helium 2012.) Helium can be refined and later stored in tanks to be sold to the market. But where exactly does the helium go after it has been refined? And in what state of matter does Helium sell at the most? It is unknown to many, but helium is actually used for more than just blowing up balloons for birthday parties.

Mercury has 121 neutrons and 80 protons in its nucleus. It also has 6 electron shells with 2 electrons in the first shell, 8 electrons in the second shell, 18 electrons in shell 3, 32 electrons in the fourth shell, 18 electrons in the fifth shell and 2 in the sixth

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 named the unknown element helium.

The name comes from the Greek God of Sun – Helios. French astronomer Jules Jannsen first detected Helium during a solar eclipse in 1868. This substance detected was initially assumed to be sodium. Although these discoveries were occurred, the formal discovery of the element was made in 1895 by Scottish chemist, Sir William Ramsay.

Helium is one of the most common elements in the universe. Helium is found mainly on the sun but can also be found in Earth’s atmosphere and is rarely found on earth. Helium is the lightest known element in the universe. It is even lighter than air. Only 0.0005% of earth's atmosphere is helium. Since its existence, helium has been the most interactive element. It has a complete shell of electrons. The main parts of this element consist of two electrons, two protons and two neutrons.

atomic no. refers to no. of protons in the nucleus (determines what each element is)

Noble Gases known for being very unreactive with other chemicals. There was an American born scientist, Linus Pauling, who theorized that they in fact could form compounds. He stated that the heavier of the noble gases could form compounds. This led to scientists researching trying to prove that his claims were in fact true. Except no one knew how to prove his claims until a accidental discovery was made.

Every element’s atoms are composed of three main subatomic particles: neutrons, electrons and protons. Located in the atom’s nucleus,

This star is made of dust ,hydrogen helium and more gases . It usually can be found in between planets. Originally nebular was a name for any diffuse astronomical object. The winds from this star are also responsible for producing the spectacular filamentary. This is a giant star that had consumed its core .helium is accumulated in the core.

On the periodic tables, there are 26 man-made elements out of 118 total elements. An isotope is a variation of an element with different numbers of neutrons in their nuclei that can have distinct properties that make them scientifically and industrially valuable. To make a stable element protons and neutrons should cancel each other out making for a more stable nucleus. To keep element making going labs will be upgraded to next-generation atomic colliders to create many different elements.

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 of He. Helium is the second lightest element after Hydrogen and considered as the least reactive element. The more an element is reactive, the more flammable it is. It is considered a non-metal element with a number of 2 stable isotopes. It is a
