Helium was first dissolved in the sun. It gets its name from the Greek word, Helios, meaning the sun
Balloons are not called helium; they can be filled with helium because this gas is not flammable and has a very low density.
Do you mean helium? Helium is an element, so it's made of .... helium!
Helium is a element named after the Greek sun god, Helios.
I'm personally not running out of helium. In fact helium is harmful to the human body in large doses. So no helium would not affect me.
Helium is a gas because its density at room temperature under one atmosphere of pressure is so low that the atoms do not form a liquid or solid.
Nuclear fusion. Most stars (the so-called "main sequence" stars) convert hydrogen-1 into helium-4.Nuclear fusion. Most stars (the so-called "main sequence" stars) convert hydrogen-1 into helium-4.Nuclear fusion. Most stars (the so-called "main sequence" stars) convert hydrogen-1 into helium-4.Nuclear fusion.

The so-called alpha particles ARE helium nuclei.

Helium ash is merely helium. Helium is commonly referred to as ash in discussions of our sun's fuel (and others stars of similar size/composition) to indicate that it cannot burn (or really cannot be fused into a larger atomic element). Our sun fuses hydrogen into helium at its core but the temperatures and pressures are not high enough to fuse helium, so it is called ash. If the core had a higher temperature/pressure, the helium would be fused into a larger element (carbon), something that happens with more massive stars. In such a star it would not be called ash because the conditions would be such that it could be fused ("burned"), so it would merely be called helium.
As we all know that noble gases are also called INERT GASES, so the subgroup VIII of GROUP 'A' contains only noble gases and inert gases so helium and neon are also in VIII-A so they are inert gases.

Helium is a nonreactive element called a noble gas.
Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).
Helium was first discovered in 1868 (145 years ago) in the sun and get its name from the Greek word, Helios, meaning the sun. So 200 years back helium was unknown and doesn't have a name.
