What can be said about the radioactive decay of a single (not a large quantity) isotope?

Radioactive decay of single isotope is a spantenous decay of the nucleus of the atoms of that isotope. It is a degradation and changing process of the isotope into energy, and other forms of particles which are spintenously released from the decaying material. The radioactive decay of an isotope follows a decay constant by which its atoms reduces and has a half-life; a time through which half of its initial mass or atoms is/are lost.

It is goin to have a long half life that is they have high stability.

Explanation:

The term radioactive decay can be defined as the spontaneous splitting or degradation of atoms of an isotope with unstable nucleus (parent nuclide) into a stable nucleus atoms (daughter nuclides). The following should be noted down for radioactive decay;

(1). Radioactive decay is a first order reaction.

(2). It is not affected by pressure.

(3). It is a spontaneous reaction ...

The radioactive decay for a single (not a large quantity) isotope has a long half life because it will take more time for it to disintegrate into another nuclide
