Nuclear Fission:
In about 400 power plants worldwide, electricity is produced from the energy liberated in a special type of nuclear reaction called nuclear fission. The word fission means to split or break up into parts. Nuclear fission is a reaction in which a heavy nucleus splits into two middleweight nuclei, releasing a lot of energy.
The process of a heavy nucleus splitting into two middleweight nuclei is called nuclear fission One of the isotopes of uranium is U-235 (235 is its mass number, ie., the sum of the number of neutrons and protons). The nucleus of U-235 can be used to start a nuclear fission reaction by bombarding it with slow-moving neutrons. In this process, U-235 itself does not undergo fission but it converts to U-236, which is highly unstable. As soon as it forms, U-236 splits in two parts.
Some neutrons, generally 2 or 3, are also emitted in this process.The nuclei of the elements formed by fission are unstable. They disintegrate further to form stable nuclei. Gamma ray (electromagnetic radiation) and particles such as neutrons and electrons are emitted by the nuclei at different stages between the fission and the creation of stable nuclei

Students / Parents Reviews [10]
A marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.

7thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.

10thMy experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
