What kind of reactions occur between the gases that make up a star? ? , As the gases in the nuclei of stars are many and varied, and these interactions that occur between them are the cause of the heat and light of the stars, and in this article we will talk in detail about the gases in the stars, and we will explain what are the interactions that occur in their nuclei. What are stars made of? Stars are large balls of explosive gases, and most of these gases are hydrogen and helium, and the closest example of these stars consisting of explosive gases is the star of the sun, where scientists believe that the nucleus of the sun is a plasma with a temperature of about 15 million degrees Celsius, which is About a mixture of electrons and protons that are stripped from hydrogen atoms, and this mixture called plasma, makes up about 90% of the sun or stars similar to it, every second that passes thousands of protons in the core of the sun or star collide with other protons to produce helium nuclei that release energy big. After that, the resulting energy moves outside the sun or star in a process called radiation, which occurs near the surface of the star, then the energy moves in the outer shell of the sun or star through a process called convection, where hot gases rise and cool, then fall again, and when they move These masses of gases, they push each other, causing what are called star quakes, and these stellar or solar earthquakes help scientists determine the internal structure of the sun or star.

The type of interactions that occur between the gases that make up the star are nuclear reactions (in English: nuclear reactions), and it can be said that the stars are giant nuclear reactors, as in the center of the stars the atoms disintegrate through huge atomic collisions that change the atomic structure of the star’s nucleus, which leads to launch it. A huge amount of energy, and this is what makes the stars very hot and bright, as happens in stars with what is called nuclear fusion, and this nuclear fusion is an atomic reaction that feeds the stars with energy, where the nuclei are many, and they unite the centers of the atoms together to form a larger nucleus that is a different element, and as a result This process is the release of a very large amount of atomic energy, where the resulting nucleus is smaller in mass than the sum of the nuclei that made it, and the difference in mass is converted into energy according to the famous Albert Einstein law, and this law is as follows: E = mc² while e is The output energy, m is the mass, and c is the speed of light. According to this law, mass, no matter how small, will be converted into a very large amount of atomic energy. See also: Why is the Sun bigger and brighter than any other star? The chemical composition of stars In the past, scientists thought that stars might be similar to Earth in chemical composition, but when they passed starlight through a prism and examined the resulting spectrum, they found that the absorption and emission lines differ. Therefore, after long astronomical studies, it was found that the chemical composition of stars differs significantly from the chemical composition of planets. Or the earth or the rest of the celestial bodies, where the stars consist of the following: Hydrogen: where the stars consist of about 90% of hydrogen gas. Helium: Stars are made up of about 9.95% helium gas. Heavy Elements: Stars are composed of about 0.05% heavy elements. At the end of this article, we learned what kind of interactions occur between the gases that make up a star? We also explained in detail what stars form and what happens inside their nuclei, and we mentioned the chemical composition of stars.
