There are 4 conservation laws in nuclear reactions. The nuclear reactions are governed by certain conservation laws which limit the possible outcome of the reaction. Some of these laws are as follows :
i) Conservation of Charge :
The total net electric charge before & after nuclear reaction should be the same.
ii) Conservation of Number of Nucleons :
In all the nuclear reactions, the total number of nucleons present before the reaction equals the total number present after the reaction.
iii) Conservation of Parity :
In all the nuclear reactions parity before the reaction should be similar to parity after the reaction.
iv) Conservation of Linear Momentum :
In all the nuclear reaction Linear Momentum before & after the reaction should be the same.
