What else can I help you with?
A nuclear chain reaction occurs when excess?
When excess neutrons are produced and collide with other atomic nuclei, it triggers a series of fission reactions, releasing more neutrons and energy in the process. This self-sustaining reaction can lead to a large release of energy in a short period of time.
What is the name of the nuclear reaction in which nuclei combine to form more massive nuclei?
The nuclear reaction in which nuclei combine to form more massive nuclei is called nuclear fusion. This process releases large amounts of energy, such as in the sun.
Where does the energy come from in a nuclear fission reaction?
In a nuclear fission reaction, the energy comes from the splitting of atomic nuclei.
What goes on when a nuclear chain reaction occurs?
A nuclear chain reaction occurs when a nucleus undergoes fission, releasing energy and more neutrons. These neutrons can then collide with other nuclei, causing them to also undergo fission and release additional neutrons. This process continues in a chain reaction, leading to the release of large amounts of energy.
How does a nuclear reactor shoot neutrons?
In a nuclear reactor, the fission process splits heavy atomic nuclei, releasing energy and additional neutrons. These neutrons can then collide with other nuclei, causing them to split and release more neutrons, creating a self-sustaining chain reaction. Controlling the number of neutrons and their interactions is crucial to the operation and safety of a nuclear reactor.
A nuclear chain reaction occurs when excess?
When excess neutrons are produced and collide with other atomic nuclei, it triggers a series of fission reactions, releasing more neutrons and energy in the process. This self-sustaining reaction can lead to a large release of energy in a short period of time.
What is the name of the reaction when hydrogen nuclei collide at high speeds to form helium nuclei?
It's a nuclear fusion reaction
A nuclear Chain reaction occurs when?
When excess electrons collide with other nuclei.
Hydrogen nuclei collide at high speeds to form helium nuclei this reaction is called?
Fusion
What is thermonuclear reaction in sun?
The thermonuclear reactions in the Sun occur in its core, where hydrogen nuclei fuse to form helium nuclei. This process releases energy in the form of light and heat, which powers the Sun and sustains life on Earth. The most common reaction is the proton-proton chain reaction, where hydrogen nuclei collide to form helium-4 nuclei.
What is the name of the nuclear reaction in which nuclei combine to form more massive nuclei?
The nuclear reaction in which nuclei combine to form more massive nuclei is called nuclear fusion. This process releases large amounts of energy, such as in the sun.
How do you complete a nuclear reaction describe the process?
In nuclear reactions, two nuclei collide and either fuse to form a heavier nucleus (fusion) or split to form smaller nuclei (fission). To complete a nuclear reaction, the colliding nuclei must overcome the electrostatic repulsion between positively charged protons to get close enough for the strong nuclear force to take over and bind them together. This process releases a large amount of energy in the form of radiation.
What is the nuclear reaction when energy is released by the joining of nuclei?
Nuclear Fusion
The splitting of nuclei of atoms is called .?
The splitting of nuclei of atoms is called nuclear fission. This process is categorized as either a nuclear reaction or a radioactive decay reaction.
What is a moderator in a nuclear reactor?
A moderator is a substance that helps slow down the neutrons so that they can collide with other nuclei to perpetuate the fission reaction (instead of just zipping by at high speeds and missing the nuclei completely most of the time).
What is a nuclear reaction in which two or more atomic nuclei come very close and then collide at a very high speed and join to form a new nucleus called?
A nuclear reaction in which two or more atomic nuclei come very close, collide at high speed, and join to form a new nucleus is called nuclear fusion. This process occurs in stars, including the Sun, where hydrogen nuclei fuse to form helium, releasing vast amounts of energy. Fusion is the source of stellar energy and has potential applications for clean energy on Earth.
What nuclear reaction happens when two small nuclei combine?
Nuclear fusion.
