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.

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 converted milligrams to grams in the first step by multiplying time 1 x 10E-3.

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)
yes king !!!

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.)

can i recommend changing your name to "Step-By Science". Its sounds catchier, otherwise the vid is really helpful
