Where were helium and and hydrogen formed?
Hydrogen was initially formed in the 'Big Bang' which initiated this universe. Helium is formed by the fusion of hydrogen atoms, inside stars. This reaction is what causes stars to shine, and give off heat.
When is hydrogen found?
Hydrogen is found in the sun and most of the stars, and is easily the most abundant element in the universe.
What two elements are found in stars?
Hydrogen and helium are the two main elements found in stars. These elements are formed through nuclear fusion in the cores of stars, where high temperatures and pressures enable the atoms to combine and generate energy.
How many percentage of the universe is hydrogen?
Hydrogen makes up about 75% of the universe by mass. It is the most abundant element in the universe and can be found in stars, gas clouds, and planets.
Is it true that Hydrogen and Helium were formed by nuclear reaction in the stars and other elements were formed after the Big Bang?
Close, but not exactly. Hydrogen is not formed by nuclear reactions in stars, hydrogen was formed not long after the Big Bang, when the expanding universe had cooled sufficiently that an electron and a proton could combine to form a hydrogen atom. Helium and all the other elements that are heavier than hydrogen, were formed by the process of nuclear fusion, in stars.
What planet could hydrogen be from?
Hydrogen is not from any planet. Hydrogen was formed in the earliest times of the universe. It is primordial. 78% of ordinary matter in the universe is Hydrogen with most of the rest being Helium. As time went on clouds of hyrdrogen collapsed and formed stars. In the centre of these stars the hydrogen and helium were converted to other elements like silicon and oxygen and iron. It is from these elements that planets were formed later. So far from hydrogen being from a planet, planets are made from hydrogen.
Why do all stars need Hydrogen and Helium?
Because without hydrogen and helium, stars wouldn't shine, not even the faintest stars! And plus if you mix them two together, there is a bang e.g helium balloon and and fire=BANG! Stars are made up of those two so that means they are a colossal fire ball, like the sun.Imagine it this way, a star was a massive helium balloon and someone got a fire burning stick and set it to this balloon, then there was a bang which is lasting millions of years!Eventually, the bang stops then this balloon explodes with energy and that's the end of that!

Why is there lots of hydrogen in the universe?
Because it is the simplest atom, and when the pure energy released at the big bang condensed into matter, it formed subatomic particles, which formed into hydrogen. The hydrogen then got turned into other things by stars.
The most common form of matter in the universe is what?
The most common found matter in the universe is plasma. Plasma, an iodized gas found mainly in stars and space, covers more than 85% of the universe.
Which is the Element abundantly present in the universe especially in stars?
Hydrogen is the most abundant element in the universe, making up 75% of ...Thiselement is found in great abundance in stars and gas giant planets.
Where hydrogen come from?
water
how much of the universe is made of hydrogen?
Roughly 75% of the normal matter in the universe is hydrogen. Hydrogen is the most abundant element in the universe and is found in stars, gas clouds, and other cosmic structures. Its simplicity and abundance make it a key building block in the formation of other elements and structures in the universe.
