Question

what is nuclear fission

Answer 1

The process in which an unstable nucleus of a heavy atom ( like U-235) splits up into two medium-sized nuclei with the liberation of an enormous amount of enengy is called nulear fission
92 U 235 + 0n1 ---> 56 Ba 141 + 56 Kr92 + 3(0n1) + energy

Answer 2

The process in which the Nucleus of a heavy atom (such as uranium,plutonium or thorium),when bombarded with low-energy neutrons,can be split apart into lighter nuclei.

atomic nuclei are made up of protons and neutrons.a Hydrogen nucleus is just a proton.a Helium nucleus comprises two protons and two neutrons,bound tightly together.what i mean by tightly bound is that it takes a lot of energy to split a helium nucleus than a hydrogen nucleus.some nuclei are easier to split.An example is Uranium-235,which is made up of 92 protons and 143 neutrons.it is quite easy to break a Uranium-235 nucleus with a neutron,it can split into a Krypton nucleus,a Barium nucleus,three neutrons and Energy.This is an example of fission.we can write the reaction briefly as

U + n --> Kr+Ba+3n+Energy

where we understand that U stands for Uranium-235,Kr stands for Krypton,Ba stands for Barium and n stands for Neutron.

Answer 3

fission means combinig of atoms

Answer 4

fussion means dividing this is easy to remember

Answer 5

splitting of heavy nucleus into lighter nucleus with releasing of energy
