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 are two elements which are abundant in nebulae?
Ionized hydrogen and helium are the most abundant chemical elements in nebulae.
When are hydrogen and helium form?
Hydrogen and helium are formed in Sun.
What are the main elements found in elements?
Hydrogen and helium
What are the first two elements to form when hydrogen nuclei undergo fusion?
The first two elements formed during hydrogen fusion are deuterium (a hydrogen isotope with one proton and one neutron) and helium-3 (a helium isotope with two protons and one neutron). This process occurs in the core of stars like our Sun.
What elements were formed during stellar evolution?
Everything except Hydrogen & Helium (and part of the Helium is also formed within stars).
What elements are produced in the sun?
From hydrogen, isotopes of helium are formed through nuclear reactions.

When are hydrogen and helium form?
Hydrogen and helium are formed in Sun.
What are the two main elements found in the stars?
Hydrogen and helium
What is the sun formed from?
hydrogen, helium, and a small amount (less than 2%) of heavier elements
Why do all stars have hydrogen and helium?
Hydrogen and helium were the first elements formed after the Big Bang, and they continue to be the most common elements in the universe due to their abundance. Stars form from clouds of gas and dust in space, and since hydrogen and helium are the most abundant elements available, they make up the majority of a star's composition.
Does helium have hydrogen in it?
No. Helium and Hydrogen are two different elements.
What do astronomers consider heavy elements?
Astronomers consider elements beyond hydrogen and helium, such as carbon, oxygen, nitrogen, and iron, as heavy elements. These elements are created through processes like nuclear fusion in stars and supernova explosions.
How are elements H an He made?
Hydrogen was formed the first by nucleosynthesis from protons; helium is obtained from hydrogen by fusion at very high temperatures.
What element formed when a hydrogen bomb explodes?
When a hydrogen bomb explodes, different elements may be formed through nuclear reactions, such as helium, lithium, tritium, and various isotopes of heavy elements like uranium and plutonium. These elements are created through the fusion and fission processes that occur during the explosion.
