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

The number of protons in the nucleus of an atom is called its atomic number.

The sum of protons plus neutrons is the mass number.

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.

The decrease in the amount of potassium required to form the original mineral has consistently confirmed the age as determined by the amount of argon formed.

Well, we're going to use exactly the same equation.

So we'll say alright, the amount at 10,000 is equal to the initial amount that I started with 1.3 times 10 to the -12 times a half to the 10,000 divided by 5700. And when you do so, you'll end up with 0.385 times 10 to the -12.

F, the fraction of K40 remaining, is equal to the amount of potassium-40 in the sample, divided by the sum of potassium-40 in the sample plus the calculated amount of potassium required to produce the amount of argon found. In spite of the fact that it is a gas, the argon is trapped in the mineral and can't escape.

(Creationists claim that argon escape renders age determinations invalid.

So, if you're trying to use his to date dinosaurs, just stop.
