Radioactive dating game answers
That means they have shorter lifetimes, producing a greater rate of decay.
For example, radium and polonium, discovered by Marie and Pierre Curie, decay faster than uranium.
After one half-life passes, half of the remaining nuclei will decay in the next half-life.
Then, half of that amount in turn decays in the following half-life.
Provided the number of nuclei is reasonably large, half of the original nuclei should decay during one half-life period.
), the number decreases to half of its original value.
Therefore, the number of radioactive nuclei decreases from A more precise definition of half-life is that each nucleus has a 50 percent chance of surviving for a time equal to one half-life.
If an individual nucleus survives through that time, it still has a 50 percent chance of surviving through another half-life.
The probability concept aligns with the traditional definition of half-life.
As a result, one would expect the amount of sample remaining to be approximately one eighth of the original amount.
