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.

How is hydrogen changed into helium in nuclear fission?
Hydrogen is not changed into helium in nuclear fission. In nuclear physics, nuclear fusion is a reaction in which two or more lighter atomic nuclei are forced together and are fused into a heavier nucleus. In the case of the formation of hydrogen into helium, our sun does that in what is called the proton-proton reaction.
What is the nuclear process that converts helium and hydrogen from lighter to heavier elements?
The nuclear process that converts helium and hydrogen into heavier elements is nuclear fusion. In this process, the nuclei of lighter elements combine to form the nuclei of heavier elements, releasing large amounts of energy in the process. This is the process that powers stars like our Sun.
What is this process called when hydrogen nuclei combine with stars to form helium and other heavier elements?
nuclear fusion reaction
The last two elements that a massive star produces are hydrogen and helium why is this the last reaction?
Hydrogen and helium are the lightest and most abundant elements in the universe. In the core of a massive star undergoing nuclear fusion, hydrogen and helium are fused into heavier elements like carbon, oxygen, and iron. Once the star reaches the stage where it can no longer sustain fusion reactions to produce heavier elements, hydrogen and helium remain as the last elements in its core before it undergoes a supernova explosion.
What are the 2 most abundant elements on the sun?
Hydrogen and helium. The nuclear fires are fueled by converting hydrogen into helium, through nuclear fusion. The core has other substances, but the sun is mostly gases.

What nuclear reaction happens between hydrogen and helium in the sun?
Nuclear fusion, in which hydrogen-1 is fused into helium-4.

Through which kind of nuclear reaction does the sun produce energy?
Nuclear fusion. Lighter elements such as hydrogen atoms get fused to produce heavier elements such as helium. While doing so enormous heat is produced.
What type of gas combines to form helium?
hydrogen combine to form helium by nuclear fusion reaction
Nuclear reaction taking place inside sun is called?
The nuclear reaction taking place inside the sun is called nuclear fusion. This is where hydrogen atoms combine to form helium, releasing a large amount of energy in the process.
What is the hydrogen to helium reaction that is occurring inside the sun called?
nuclear fission
What nuclear reaction combines gas to form helium and produce most of the suns energy?
The nuclear reaction that combines hydrogen to form helium and produces most of the sun's energy is called nuclear fusion. In this reaction, hydrogen nuclei (protons) fuse together to form helium nuclei, releasing a large amount of energy in the form of light and heat.
Can helium be turned into hydrogen to produce energy?
Helium cannot be turned into hydrogen to produce energy. Helium and hydrogen are two different elements with different atomic structures and properties. However, fusion reactions involving hydrogen isotopes such as deuterium and tritium can produce energy in a process known as nuclear fusion.
What elements are produced in the sun?
From hydrogen, isotopes of helium are formed through nuclear reactions.
