Concept introduction:
The nuclear reactions are a type of chemical process which leads to the formation of some new nuclei with the emission of certain particles. Usually, alpha or beta particles or gamma rays are emitted as a side product with some new daughter nuclei. The nuclei which show spontaneous decay with time are known as radioactive nuclei.
(b)
Interpretation:
The possible pathway should be determined out of given two pathways on the basis of energy change.
Concept introduction:
In an atom, three sub-atomic particles are arranged in a certain way to make the atom stable. The nuclear attraction force works between electrons and protons due to opposite charges. The force between protons and neutrons holds these particles together. It can be measured by measuring the amount of energy necessary to break these forces.
It can be calculated with the help of Einstein’s mass-energy equation:
The mass defect can be calculated as the difference in the
