When a nucleus with atomic number Z and mass number A undergoes a radioactive decay process,
(1) Both Z and A will decrease, if the process is α decay.
(2) Z will decrease, but A will not change, if the process is β+ decay.
(3) Z will increase, but A will not change, if the process is β− decay.
(4) Z and A will remain unchanged, if the process is γ decay.
Why this Question ? To know the basic definition about α, β−,γ and β+decay. |
