By a nuclear fusion reaction: H + H + 2n ==>> He

Yes, this is true. I want, here, to put it into a better picture for common folk. This Bang is similar to the nuclear furnace that is out Sun. There, hydrogen atoms are fusing to other hydrogen atoms. It happens because gravity strength forces them together. The result is a helium atom(s) plus excess energy. That excess radiation is what blinds you when you try to look at the sun.

What produced the helium now present in the sun's core?

The big bang produced the helium no present in the sun's core. The universe cooled down enough after the big bang to form the formation of helium and hydrogen.

What were atoms heavier than helium were made by?

Atoms that are heavier than hydrogen were made by nuclear fusion after the big bang. Initially, only the lightest element, hydrogen, was present. However, after the universe cooled, hydrogen atoms fused to form helium. Later, the fusion of these atoms led to the formation of the other elements.


What is The joining of hydrogen atoms of form helium?

Nuclear Fusion


What combines to form helium atoms in a star?

Helium atoms in a star are formed through the process of nuclear fusion. In the core of a star, hydrogen atoms combine through a series of fusion reactions to form helium atoms. This happens when hydrogen atoms collide and fuse together, releasing energy in the process.


Number of hydrogen atom fuse to form helium atom?

2 hydrogen atoms


In a star atoms combine to form helium atoms?

Hydrogen- the only atom smaller


What fusion in stars occurs to create the element helium?

Hydrogen undergoes nuclear fusion in the core of the sun to form helium.


What factor allowed the sun to form in the solar system?

The sun was formed after a high concentration of hydrogen and helium collapsed in upon itself soon after the big bang and began fusing the atoms.


How did the big bang theory form the sun?

Hmph. The Big Bang theory did not form the sun. The big bang formed the elements hydrogen, then hydrogen began to create helium. Then stars were formed out of these two elements and that is how our sun was created.
