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.)
In the fusion reaction on the sun what happens to hydrogen that does not convert into helium?
It just stays there waiting to be used-the sun has enough to last many billions of years and luckily for us the rate of burning has stayed fairly constant so far, but eventually it will run out of hydrogen and die.
How many helium nuclei fuse together when making carbon?
Three helium nuclei, also known as alpha particles, fuse together to form a carbon atom in the process of stellar nucleosynthesis.
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 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
How many hydrogen atoms that fuse to form a helium is?
In nuclear fusion, four hydrogen atoms combine to form one helium atom. This process releases a large amount of energy in the form of light and heat. It is the primary energy-producing process in stars like the Sun.
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.
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.
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.)
Hpw many percent of hydrogen and heliumdoes the sun has?
The sun is made up of 71% hydrogen, 27.1% helium.
How many elements are there in the first period of periodic table?
There are 2 elements in the first period of the periodic table: Hydrogen and Helium.
How many protons and neutrons are in the nucleus of a helium-4 atom if it has twice as many protons as a hydrogen atom?
A hydrogen atom has 1 proton in its nucleus. Since the helium-4 atom has twice as many protons as hydrogen, it has 2 protons. Helium-4 also has 2 neutrons, hence the name "4" representing the total number of protons and neutrons.
Why does the sun not run out of hydrogen?
It will eventually. In about 5 billion years the sun will deplete the hydrogen at its core. Afterward it will continue to alternate between fusing helium in the core and fusing hydrogen in a shell around the core before it finally dies.
