What are fission reactions?

Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay.

What happens during fission?

In fission, the nucleus splits, either through radioactive decay or because it has been bombarded by other subatomic particles known as neutrinos. The resulting pieces have less combined mass than the original nucleus, with the missing mass converted into nuclear energy.

What happens to the nucleus during fission?

Nuclear fission is a process by which the nucleus of an atom is split into two or more smaller nuclei, known as fission products. The fission process also releases extra neutrons, which can then split additional atoms, resulting in a chain reaction that releases a lot of energy.

Where does fission and fusion occur?

Fission is the splitting of a large atom into two or more smaller ones. Fusion is the fusing of two or more lighter atoms into a larger one. Fission reaction does not normally occur in nature. Fusion occurs in stars, such as the sun.

What is fission fusion?

Both fission and fusion are nuclear reactions that produce energy, but the processes are very different. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.

What is the primary result of a fission reaction?

👍 Correct answer to the question What is the primary result of a fission reaction? (1) conversion of mass to energy (2) conversion of energy to mass (3) binding together of two heavy nuclei (4) binding together of two light nuclei – e-eduanswers.com

Which reaction produces more energy,fission or fussion?

Answer. Fission only produces more energy than it consumes in large nuclei (common examples are Uranium & Plutonium, which have around 240 nucleons (nucleon = proton or neutron)). Fusion only produces more energy than it consumes in small nuclei (in stars, Hydrogen & its isotopes fusing into Helium).

What are the most important fission reactions?

The most important nuclear fission reaction that is exploited in nuclear reactors is that of uranium-235, one of the isotopes of natural uranium. Uranium-235 makes up only 0.7\% of natural uranium but is the key atomic species for the generation of nuclear power. Uranium-235 is naturally radioactive with a half-life of 704 million years.

What are the elements produced by a fission reaction?

Uranium and plutonium are most commonly used for fission reactions in nuclear power reactors because they are easy to initiate and control. The energy released by fission in these reactors heats water into steam. The steam is used to spin a turbine to produce carbon-free electricity.
