Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample.The creationist "argon escape" theory does not support their young earth model.) The argon age determination of the mineral can be confirmed by measuring the loss of potassium.In old rocks, there will be less potassium present than was required to form the mineral, because some of it has been transmuted to argon.

For example, uranium-238 is an isotope of uranium-235, because it has 3 more neutrons in the nucleus.

Many geologists claim that radiometric “clocks” show rocks to be millions of years old.

However, to read any clock accurately we must know where the clock was set at the beginning.

Potassium-Argon dating: The element potassium (symbol K) has three nuclides, K39, K40, and K41. K40 can decay in two different ways: it can break down into either calcium or argon.

The ratio of calcium formed to argon formed is fixed and known.If we knew the fraction of a radioactive element still remaining in a mineral, it would be a simple matter to calculate its age by the formula To determine the fraction still remaining, we must know both the amount now present and also the amount present when the mineral was formed.
