What atomic nuclei were formed in the big bang?
Hydrogen, helium, and a small amount of lithium. If the BB is an accurate description of the early existence our Universe, then the ratio of hydrogen to helium to deuterium would be a certain value. The actual ratio matches the prediction of the BB quite well.
What gas is produced by nuclear fusion?
In the most common stellar fusion, helium gas is formed from the fusion of hydrogen nuclei.
The helium flash converts helium nuclei into?
carbon
What happened 3 mintues after the big bang?
Neutrons combined with protons to form the Universe's deuterium and helium nuclei in a process called the Big Bang nucleosynthesis
What will the helium become when it grows up?
Helium is an inert gas; it does not react in any chemical reactions. It does not form any molecules. Helium is formed in the Sun as the result of the fusion of hydrogen nuclei in nuclear fusion. In the cores of dying stars, helium will fuse into carbon and other heavier elements.
What element is formed when hydrogen nuclei fuse together?
Helium
This type of nucleus is formed during a solar nuclear reaction by the fusion of four nuclei.?
helium

Are beta particles the same as helium nuclei?
B- particles are electrons. They are not Helium nuclei.
What gas is produced by nuclear fusion?
In the most common stellar fusion, helium gas is formed from the fusion of hydrogen nuclei.
What type of nucleus is during a solar nuclear reaction by the fusion of four nuclei?
A helium nucleus is formed from four protons.
The helium flash converts helium nuclei into?
carbon
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
What happened 3 mintues after the big bang?
Neutrons combined with protons to form the Universe's deuterium and helium nuclei in a process called the Big Bang nucleosynthesis
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.
Why was hydrogen and helium formed?
Hydrogen is the simplest element; we believe that seconds after the Big Bang, all the mass in the universe was hydrogen. But because the heat and pressure were so intense, some of the hydrogen immediately fused into helium, or into lithium. (It takes four hydrogen nuclei to fuse to make helium, and six hydrogen nuclei will fuse into lithium.) This is all guesswork, of course; we weren't there, and have only the haziest understanding of what the conditions of the Big Bang might have been like - or if there was something else entirely happening that we currently can't image.
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.
