no, as a hydrogen burning main sequence star.

Hydrogen and Helium
the theaory of gravity when lifted by a hot air substance is qiute simple if you think about it
The atmospheric gas of Earth consists of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.03 percent carbon dioxide, with hydrogen, water, ozone, neon, helium, krypton, xenon, and traces of other elements making up the remaining 0.07 percent.
The chemical symbol for helium is "He."
it is fusion of hydrogen into helium. (like our sun) if it is a red giant (the next stage of our suns life) it is burning helium into denser things.
No, a red giant is a star that has just left the hydrogen burning main sequence and begun the next step, burning helium. As helium undergoes fusion at a much higher temperature than hydrogen undergoes fusion, the star expands dramatically and as it expands its outer layers cool to red heat.
Basically, the stars on the "Main Sequence" are the ones that fuse hydrogen-1 into helium-4. Once a star burns up its hydrogen-1 fuel, or doesn't have much left, it will start burning helium-4 into heavier elements. It is then that the star leaves the "Main Sequence".
Helium does not catch fire
Helium builds up in the core, while the hydrogen burning shell expands.
3 He fuse to 1 C. Note you HAVE to skip Beryllium in the fusion sequence, it won't let you get by it if you try going through it.
Nothing, helium is inert.
Stars fuse hydrogen into helium during the main sequence. After the main sequence, helium, oxygen, silicon and carbon are fused.

99.993 % into Helium, .007 % into energy.
Hydrogen and Helium
helium is made from the sun from the atmosphere and is believed to have a percentage of 70 percent. Well, actually, helium isn't made in the sun. But even then, the atmosphere of the sun is actually made up of 54% helium to be exact. (Not far off from what you said, though.) Correction: Helium IS produced in the sun! hydrogen is fused into helium and this liberates large amounts of energy.
