How is potassium 40 formed
WebSo there is 8.7 percent of the potassium-40 is still remaining in the Earth. An alternative method would be to say that the number of atoms equals the original number of atoms multiplied by one-half to the power of the number of half-lives that have elapsed. WebWe don't have a good way to determine how much Ca-40 the sample started with though, so we can't use it to determine which portion formed from K-40 decay. We only use Ar …
