The mass which is lost during the decay is called the
mass
effective mass
mass defect
mass of proton
Nuclear energy is
the energy obtained from the total mass during a radioactive decay
the energy obtained from the mass defect during an isotope making
the energy obtained from the total mass during a fusion reaction
the energy obtained from the mass defect during a radioactive decay
Which is incorrect?
E = energy released (J)
m = mass defect (kg)
m = total mass (kg)
c = speed of light
Nuclear Fission
is a process of splitting a heavy nucleus into two lighter nuclei. Accompanied with the release of enormous amount of energy from the mass defect
is a self-sustaining reaction in which the products of the reaction can initiate another similar reaction. Accompanied with the release of enormous amount of energy from the mass defect
is a process of combination of two lighter nuclei to form a heavier nuclei. Accompanied with the release of enormous amount of energy from the mass defect
This is a
chain reaction
nuclear fusion reaction
nuclear fission reaction
atomic mass defect reaction
Radium-226 undergoes alpha decay to become radon-222. The equation is :
