Question

write the features of nuclear fission and nuclear fusion?​

Answer 1

Answer:

Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. 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.

Both nuclear fusion and nuclear fission use the energy stored in atomic particles in the energy production process. ... All elements have proton particles in the nucleus, and electrons, which are much smaller particles, outside.

Answer 2

Answer:

Explanation:

The harnessed nuclear energy is released in nuclear reactions. There are two types of nuclear reactions called nuclear fission and nuclear fusion. Nuclear fission and fusion involve the disintegration and combination of the elemental nucleus. In the case of nuclear fission, an atom divides into two or smaller or lighter atoms. Nuclear fusion occurs when two or more atoms join or fuse together to form a large or heavy atom.

Nuclear Fission: The word fission means division or splitting. As per the meaning in the nuclear fission reaction, the nucleus of an atom is bombarded with low energy neutrons which split the nucleus into smaller nuclei, this process is called nuclear fission. An abundant amount of energy is released in this process. Nuclear fission reactions are used in nuclear power reactors since it is easy to control and produces large amounts of energy.  

Example: when uranium-235 atoms bombard with neutrons, the heavy nucleus of the uranium splits and produces krypton-94 and barium-139 with the emission of three neutrons.

Nuclear Fusion: Nuclear Fusion is a reaction that occurs when two atoms combine together to form one or more different atomic nuclei and subatomic particles like protons and neutrons. An enormous amount of energy is released in this process and is greater than the nuclear fission reaction.

Example: Fusion occurs in the sun where the atoms of (isotopes of hydrogen, Hydrogen-3, and Hydrogen-2) Deuterium and Tritium combine in a huge pressure atmosphere with extremely high temperatures to produce an output in the form of a neutron and an isotope of Helium.
