What is the main fuel of stars?
The main fuel of stars is the most fundamental element in the universe -- hydrogen. Most stars spend most of their lives fusing hydrogen into helium. Only later in life do they fuse helium into heavier elements, and continue to fuse lighter nuclei into the elements up through iron. (According to many scientists, nickel really does not "count" in this chain for reasons that require an understanding of nuclear physics.)
How many helium nuclei fuse together when making carbon?
3
How many gases does the sun have?
2/3 hydrogen, 1/3 helium
Where does the energy for the fusion come from in red giant star?
Nuclear fusion comes from the sun it is a "fusion" of hydrogen pairs that make helium and the helium has to many electrons so those extra turn in to photons and come to earth from the sun as heat and light. Or that's what i have heard. So this happens in the sun very rapidly many photons are sent to the earth each second.So the answer (or what i think is the answer) is it comes from the sun!
Is it true that the sun is composed mostly of hydrogen and helium?
Stars are made up of mostly hydrogen and helium. These two gasses comprise most of the universe, and formed some 300,000 years after the big bang, after matter decoupled from the electromagnetic force and the temperature of the universe had sufficiently cooled.
How many hydrogen atoms that fuse to form a helium is?
two hydrogen atoms
How do all stars get their energy during most of their lifetime?
Stars get most of their energy through nuclear fusion. Mainly, the fuse hydrogen to helium. However, many stars will eventually fuse helium to the so-called "metals", meaning any element heavier than helium.
What is the name of a very light gas used in balloons many years ago?
helium or hydrogen
What gas makes up the majority of an old star?
Even in an old star just before it explodes, the majority of the star in hydrogen gas. But as the hydrogen is fused, the helium residue begins to interfere with the hydrogen fusion, like ashes in the bottom of a fireplace.
How many electrons does it take for hydrogen and helium to become stable?
Helium is already stable. Hydrogen should gain or lose one electron to be stable.
What ions are emitted by the sun?
many, but mostly hydrogen and helium.
Which nuclear fuel is there in the sun?
At this point in time hydrogen is being fused into helium. Many, many years down the line, as the hydrogen runs out, the sun will begin fusing heavier and heavier elements for fuel. At least to iron.
What is major gas in a star?
Stars are made mostly of hydrogen though there are many other elements that help to build one. And toward the end of its life cycle a star will actually be made of a large portion of helium as well which it will begin to fuse, along with hydrogen or instead of hydrogen, in its core.
How many shells does hydrogen have?
All elements in the first period have 1 shell. That's hydrogen and helium.
What is the main fuel of stars?
The main fuel of stars is the most fundamental element in the universe -- hydrogen. Most stars spend most of their lives fusing hydrogen into helium. Only later in life do they fuse helium into heavier elements, and continue to fuse lighter nuclei into the elements up through iron. (According to many scientists, nickel really does not "count" in this chain for reasons that require an understanding of nuclear physics.)
How many energy levels would electrons of hydrogen and helium fill?
1st energy levels only in which hydrogen will have only one electron whereas helium will have two electrons.
How many different types of atoms are in helium?
Helium is an element, so it is made of only one type of atom.
