Carbon dating equation with half life

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.

Here we will explore half-life and activity, the quantitative terms for lifetime and rate of decay. The answer can be found by examining Figure 22.27, which shows how the number of radioactive nuclei in a sample decreases with time.

Therefore, the decay of a nucleus is like random coin flipping.

The chance of heads is 50 percent, no matter what has happened before.

The probability concept aligns with the traditional definition of 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.
