Radioactivity and radioactive dating

The ratio of calcium formed to argon formed is fixed and known.

Therefore the amount of argon formed provides a direct measurement of the amount of potassium-40 present in the specimen when it was originally formed.

I know can be hard to wrap your head around, so let's model it with a six-sided die. You can use Lego bricks, pennies, beans—anything you can easily count. Every time you roll a one, put that object into a separate pile.

Count the remaining objects and repeat the process until half of them have decayed. It took a while, but we finally got pretty close to 40 tiles left.

Strontium-87 is a stable element; it does not undergo further radioactive decay.

(Do not confuse with the highly radioactive isotope, strontium-90.) Strontium occurs naturally as a mixture of several nuclides, including the stable isotope strontium-86.

However, any escaping argon gas would lead to a determined age younger, not older, than actual.

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.

Because argon is an inert gas, it is not possible that it might have been in the mineral when it was first formed from molten magma.
