Radioactivity (11 of 16) Radioactive Decay Law, An Explanation

Explains what the radioactive decay law is. It states that the number of parent nuclei in a radioactive sample decreases exponentially over time. Includes a full explanation and a worked example for calculating the number of radioactive nuclei that remain after a specific amount of time. Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation in the form of alpha, beta and gamma particles.

1 mg of I-131 should be 7.64*10^-6 atoms

Thank you so much! Your video is so easy to understand!

Thanks, there was problem solved along with your explanation

Thank you for your explanation, but because you haven't converted the milligram to the grams the whole calculation turned incorrect, therefore, the correct answer is 6.22*10^16 atoms
