Uppoe you have 100,000-atom ample of a radioactive nuclide that decay with a half life of 2. 0 day. How many radioactive atom are left after 10 day?

Respuesta :

After 10 days, there will be approximately 15,625 radioactive atoms left.

What is radioactive?
The process through which an unstable nucleus loses energy through radiation is known as radioactive decay, also recognised as nuclear decay, radioactive contamination, radioactive disintegration, as well as nuclear disintegration. A substance that has unstable nuclei is regarded as radioactive. Alpha decay, beta decay, and gamma decay are three of the most frequent types of decay, and they all involve the emission of one or even more particles. Beta decay is a result of the weak force, while the nuclear force and electromagnetism are in charge of the other two mechanisms. Electron capture, which occurs when an unstable nucleus seizes an inner electron in one of the electron shells, is the fourth common type of decay.

This is because the half life of the nuclide is 2 days, meaning that after 2 days, half of the 100,000 atoms will have decayed and only 50,000 atoms will remain. After 10 days, the number will have halved 6 times, leaving 15,625 atoms (50,000/2^6).
