A pure sample of radioactive nuclide X decays into a stable nuclide Y.What is number of atoms of Ynumber of atoms of X after two half-lives
Question
Solution 1
After one half-life, half of the atoms of the radioactive nuclide X have decayed into the stable nuclide Y. This means that the number of X atoms has decreased to half, and the number of Y atoms is now equal to half the original number of X atoms.
