Most commonly, a hydrogen nuclei is simply a proton. If you are dealing with a hydrogen isotope (H2 or H3) then it is a proton and 1 or 2 neutrons. Most commonly, a hydrogen nuclei is simply a proton. If you are dealing with a hydrogen isotope (H2 or H3) then it is a proton and 1 or 2 neutrons.

What accurately describes the main reaction that generates the Sun's light?
hydrogen nuclei fuse forming helium and releasing energy
What is para and ortho hydrogen?
A molecule of diatomic hydrogen (hydrogen gas) contains two hydrogen atoms. The nucleus of each aton (a protron) is spinning. Depending upon the direction of the spin of the two nuclei, the hydrogens are of two types: ortho or para. Ortho-hydrogen molecules are those in which the spins of both the nuclei are in the same direction. Para-hydrogen is when the spins of both the nuclei are in the opposite directions. Ordinary hydrogen gas is an equilibrium mixture of ortho and para hydrogen. The amount of ortho- and para-hydrogen varies with temperature. At 0°K, hydrogen contains mainly para-hydrogen which is more stable. At the temperature of liquid of air, the ratio of ortho- and para-hydrogen is 1 : 1. At the room temperature, the ratio of ortho- to para-hydrogen is at its maximum of 3 : 1. Even at very high temperatures, the ratio of ortho- to para-hydrogen can never be more than 3 : 1. So, it is possible to get pure para hydrogen by cooling ordinary hydrogen gas to a very low temperature (close to 20 K) but it is never possible to get a sample of hydrogen containing more than 75% of ortho hydrogen.
Which element in the universe was made after the big bang before any stars where made?
Scientists reckon that Hydrogen nuclei were the first to form (being the most simple element), around a few milliseconds after the `big bang`. Between 3 and 20 minutes they reckon that helium nuclei were the next to be formed. They then say that these nuclei were not able to capture electrons until around 379,000 years later.
When the two hydrogen nuclei fuse what is the composition of the resulting nucleus What particle has been changed?
Helium
Why can nuclei of carbon oxygen and iron be found in stars?
Nuclear fusion between nuclei of smaller atoms forms the nuclei of larger atoms and releases energy.
What gas is the center of the sun made of?
- hydrogen nuclei waiting to be fused into helium and - helium which has been fused from hydrogen nuclei
How are hydrogen nuclei different from helium nuclei?
The main difference is that hydrogen nuclei have 1 proton whereas helium nuclei have 2 protons. The number of neutrons depends on the "isotope". Usually, a hydrogen nucleus does not have neutrons and is simply a proton. The helium nucleus usually has 2 neutrons.
What nuclei bond together during the solar nuclear reaction?
Hydrogen nuclei, which are protons
What is the distance between nuclei in a hydrogen molecule br2?
74 pm from nuclei to nuclei.
What nuclei are fused in the nuclear reaction of a hydrogen bomb?
Deuterium (heavy hydrogen) nuclei and tritium nuclei to form helium nuclei. This comes from lithium deuteride in modern "dry" hydrogen bombs. Neutrons from fission splits the lithium generating tritium just before fusion is ignited..
What does the sun convert into helium?
Hydrogen Nuclei
Which pair of nuclei can undergo a fusion reaction?
Hydrogen-2 and hydrogen-3
Hydrogen nuclei collide at high speeds to form helium nuclei this reaction is called?
Fusion
How does the sun create energy and where does it happen?
By nuclear fusion of hydrogen nuclei into helium nuclei, in the core.
When the sun burns hydrogen helium it makes what?
The sun is on the Main Sequence, fusing hydrogen nuclei to form helium nuclei and release substantial quantities of energy.
How are hydrogen 1 and hydrogen 2 alike?
Hydrogen-1 and hydrogen-2 are alike in that they both have one proton in the nuclei of their atoms.
What happens in the core that marks the birth of a star?
Nuclear fusion, converting hydrogen nuclei into helium nuclei.
