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 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

    He did convert mg to g but still his calculation I THINK is wrong cz i did exactly what he did and my answer is the same as yours (6.117×10^16 atoms)

    Google it, there should also be an e button on your calculator. e in Euler's number. The value of e is 2.718281828459045… (like pi it goes on forever.)
