What are the two main elements of the sun?
Hydrogen and Helium. Also comprised of a core of much heavier elements, all the elements in the universe heavier than hydrogen probably came from supernovae.
Is the sun made mostly of hydrogen and helium true or false?
True. The Sun is mainly composed of hydrogen (about 74% of its mass) and helium (about 24% of its mass). The remaining 2% consists of trace amounts of heavier elements.
The two elements most abundant in the universe are?
Hydrogen and helium are the two most abundant elements in the universe.
What is heavier nitrogen or helium?
Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).
Where are common elements made?
All elements past hydrogen are formed in stars. During the main stage of stars life, it fuses hydrogen into helium. Once it runs out of Helium to fuse, it begins fusing Helium into heavier elements. This continues until iron is formed. Iron gains no energy from fusion, so fusion stops. If the star is massive enough, it will explode in a supernova. The extreme heat can cause the iron to fuse into even heavier elements.

Is helium lighter or heavier than hydrogen?
Heavier but safer. Look what happened to the Hindenburg:(
What is lighter than helium but heavier than air?
hydrogen
What is the fuel of a star in space?
Hydrogen , Helium and a few heavier elements.
What element does a star run out of that causes them to die?
Hydrogen and helium; those two elements are the fuel for the stars. First they fuse hydrogen to helium, later they fuse helium to heavier elements.
What gases are heavier than helium?
Helium exists as a monatomic gas, with atomic mass of 4.0. Thus any gas with a molecular mass higher than 4.0 would be heavier than helium. Hydrogen is the only gas that is lighter than helium; all others are heavier than helium.
Immediately after the Big Bang the universe contained?
Hydrogen, helium, small amounts of lithium. No heavier elements. Lots of the mysterious dark matter.Hydrogen, helium, small amounts of lithium. No heavier elements.

What Fuel does a Star burn to create its own energy?
A star will use fusion to combine lighter atoms into heavier atoms. A main-sequence star (that's the majority of stars) will convert hydrogen-1 into helium-4, so in this case, hydrogen-1 is the fuel. Once it starts running out of hydrogen-1, it will start fusing the helium into heavier elements - in which case the main fuel will be the helium-4. Later in the life cycle of a star, the fuel can be even heavier elements.
Do all stars turn hydrogen in to helium?
No. Stars that have depleted the hydrogen in their cores may start fusing heavier elements.
What is the sun formed from?
hydrogen, helium, and a small amount (less than 2%) of heavier elements
What is Saturn's material composition?
About 75% hydrogen and 25% helium, with some traces of heavier elements.
