Question

At what condition does the nucleus of an atom become
radioactive?

When does the nucleus of an atom, tend to be radioactive? ​

Answer 1

Answer:

Inside the stable nucleus, the protons and the neutrons exist together. But when the number of neutron becomes greater than that of protons, then the nucleus becomes unstable which results in the conversion of a neutron into a proton emitting a beta particle in the process. Then a nucleus is said to be radioactive.

Answer 2

Answer:

(1) Inside the stable nucleus, the protons and the neutrons exist together. But when the number of neutron becomes greater than that of protons, then the nucleus becomes unstable which results in the conversion of a neutron into a proton emitting a beta particle in the process. Then a nucleus is said to be radioactive.

(2) When the atomic number of an element is more than 82, it becomes radioactive because ...in their nuclei, the number of neutrons is much more than the number of protons.
