Question

radioactivity ❤️....​

Answer 1

❤️Radioactivity refers to the particles which are emitted from nuclei as a result of nuclear instability. Because the nucleus experiences the intense conflict between the two strongest forces in nature, it should not be surprising that there are many nuclear isotopes which are unstable and emit some kind of radiation.❤️

Answer 2

$\small\boxed{Radioactivity}$

The emission of elementary particles by some atoms when their unstable nuclei disintegrate (see half-life).

I hope its help for you:)
