What is meant by redio activity
Solution:
We define radioactivity as the spontaneous emission of particles (alpha particles, beta particles, neutrons) or radiations (range, K capture), or both at the same time, coming from the disintegration of certain nuclides that form them, due to an arrangement in its internal structure.
During one alpha decay, the mass number is decreased by 4 and the atomic number by 2.
For each beta decay, the mass number remains unchanged, and the atomic number increases by one.
