Half lives formula used 2n=[a0]/at where n= half lives Given you start with 50g of the material, how many minutes will pass before you have 5g left? O 1. 72 minutes o 15. 95 minutes o 9. 60.

When an unstable radioactive atom decays, it usually turns into: A more stable atom. In the nuclear equation below, calculate the mass number of the alpha particle. Advanced physics questions and answers.

### How to Do Half-Life Problems of Radioactive Isotopes

How to solve half-life problems chemin10.com Determine the half-life of a radioactive isotope, the time taken to fall to half its original value. What is the half-life of an isotope and how to do half-problems. This lesson covers how to solve half-life problems, including solving for the half-life of a radioactive isotope, determining the amount remaining after a specified amount of time has passed, the original amount present, and the amount of time that has passed, the latter of which is used to determining the age of a fossil using carbon-14 dating. In this chemistry lesson, you will learn: how to read an exponential decay curve …
