The following nuclei are observed to decayby emitting a β- particle a. 18 F b. 22 Na Write out the deacy process for each of these nuclei, anddetermine the energy released in each reaction. Be sure to takeinto account the mass of the electrons associated with the neutralatoms.
OpenStudy (anonymous):
When a beta minus particle is released, the nucleus ends up with one less neutron and one more proton. This means the element left behind is one place up on the periodic table. To find the energy released you will need to know the mass of all the particles before the decay and then the mass of all the particles after the decay. There should be less mass after the decay than before. This difference in mass will cause a release in energy according to the equation:E=mc 2
