Choose an isotope and describe its radioactive decay process and how it is used.

I choose Carbon-14 isotope

Radioactive decay process of Carbon-14 isotope:

C decays by a process called beta decay. During this process, an atom of 14C decays into an atom of 14N, during which one of the neutrons in the carbon atom becomes a proton. This increases the number of protons in the atom by one, creating a nitrogen atom rather than a carbon atom.

Application of Carbon -14 decay:

Carbon-14 has a half-life of 5,730 years and a decay rate of 14 disintegrations per minute (dpm) per gram of natural carbon.

For example, If an artifact or historical piece is found to have radioactivity of 4 dpm per gram of its present C, we can find the approximate age of the object using the below equation:

Thus, age of this historical artifact is 10356 years.

Kindly do like if It Helped!
Thank you!!!

Radioactive decay can be used to determine the age of an object. If you know the number of radioactive nuclei with which an object started, the number of radioactive nuclei currently present, and the half-life of the isotope, you can calculate the time since the object was created.
