Where is Helium Found Helium is the second lightest element in the known universe. It is also the second most abundant. According to some estimates helium accounts for as much as 24 percent of the Universe’s mass. This element is also plentiful since it is a prime product of fusion nuclear reactions involving hydrogen. So if it is so plentiful where is Helium found?

ASTRONOMY 101 B. All but 2% of the mass in the universe is hydrogen and helium. 2% of the mass of the universe is hydrogen and helium, the rest is heavier elements. All but 2% of the mass of the universe is hydrogen. The universe contains about ten times as many hydrogen atoms as helium atoms, but a helium atom has four times the mass of a hydrogen atom.

Abundance of the chemical elements Abundance (atom fraction) of the chemical elements in Earth's upper continental crust as a function of atomic number. The rarest elements in the crust (shown in yellow) are the most dense. They were further rarefied in the crust by being siderophile (iron-loving) elements, in the Goldschmidt classification of elements.

- The existing atmosphere surrounding the earth contains a little less than one percent of the inert gas Argon, an approximate total of 6.59 x 1019 grams. The isotope Argon-40 (40AR) is 99.6 percent of the total Argon. The only know source of 40Ar is the radioactive decay of Potassium-40 (40K), of which 11.2 percent decays into 40AR and the remainder into Calcium-40 (40CA).

Helium: the essentials Helium is present in the atmosphere at about 0.0005% (1 part in 200000) by volume and is an important component within hydrocarbon gases in the USA. Its origin in these gases is traced to the decay of radioactive elements in rocks. Some minerals contain occluded helium and this can be liberated by heating.elium is the second most abundant element in the universe. It is very common in the hotter stars. It is an important component in the proton-proton reaction and the carbon cycle in stars.

The Star In You The Big Bang also churned out helium, the next lightest element. You don't have any helium in you, unless you just sucked the gas out of a birthday balloon. But helium is the second most common element after hydrogen. Together they make up more than 98 percent of the matter in the universe.

Abundance of the chemical elements As another example, looking at the mass-fraction abundance of hydrogen and helium in both the Universe as a whole and in the atmospheres of gas-giant planets such as Jupiter, it is 74% for hydrogen and 23-25% for helium; while the (atomic) mole-fraction for hydrogen is 92%, and for helium is 8%, in these environments.

- The Most Abundant Elements. With only one proton, hydrogen is the simplest, lightest element, followed by helium, which has two protons. At 75 percent, hydrogen is also the most abundant element in the universe, followed again by helium at 23 percent, then oxygen at 1 percent. Each oxygen atom has eight protons.

- As a result, it has been estimated that there are around 1,100,000 metric tonnes of helium-3 on the surface of the Moon down to a depth of a few metres. This helium-3 could potentially be extracted by heating the lunar dust to around 600 degrees C, before bringing it back to the Earth to fuel a new generation of nuclear fusion power plants.

HE-LI-UM Even when first discovered and identified, scientists knew there were large amounts of helium in the Sun. Similar to hydrogen (H), helium is usually found as a gas and has no color or smell. Helium is found everywhere in the Universe and is the second most common element, just behind hydrogen. As far as we're concerned, helium is a happy element.

The Most and Least Abundant Elements How about the Universe? Which are the most abundant elements in the Universe? Some of you may have guessed it-hydrogen followed by helium. It is now estimated that hydrogen forms about 73.9% by mass of the universe, helium about 24%, oxygen (about 0.1%) and carbon about 0.046%. All other elements are estimated to be at trace levels.

Abundance of the chemical elements Although hydrogen and helium make up respectively ≈ 92 and ≈ 7% of the baryonic matter in the universe, the other elements i.e. the remaining 1% is huge masses that have led to the emergence life. The abundance of elements decreases exponentially with the atomic number (Z).

Why Does Inhaling Helium Make Your Voice Sound Funny? Helium's atomic number is 2 and its atomic weight is 4.002602. Its boiling and melting points— -452.1°F and -458.0°F, respectively—are the lowest among the elements. It is the second most abundant element in the known universe (after hydrogen). And it makes your voice sound really funny when you inhale it. Here's why.

Comparison of Abundance of Elements On top of the earth’s crust is an atmosphere, this is a thin layer of gases, 95% of these gases are within the first 20km of the earth’s surface. Of the 17 elements that make up 99.5%, the most abundant of these are Oxygen 49.2%, Silicon 25%, and Aluminum 7.5%.

- The Earth is constantly degassing, which transports helium from the crust and mantle into the oceans and atmosphere. Because it is such a light atom, helium escapes from Earth and is thereby continually lost from the atmosphere. The approximate lifetime of helium in the atmosphere is ~ 1 to 2 Myr.

- Helium deposits in the earth's crust are thought to have been created by radioctive decay of elements like uranium and thorium. But the largest naturally occuring source of helium is found in natural gas.elium (and the other noble gases that are normally chemically unreactive) are found in volcanic gas emissions. But unless it is really, really large you're not going to be mining it for helium; there just wouldn't be enough to collect there to make it worthwhile.

Noble gas The abundances of the noble gases decrease as their atomic numbers increase. Helium is the most plentiful element in the universe except hydrogen. All the noble gases are present in Earth’s atmosphere and, except for helium and radon, their major commercial source is the air, from which they are obtained by liquefaction and fractional distillation.
