So this is beta decay. If I wait carbon's half-life-- this is a specific isotope of carbon. If you want to go even further back, you can look at cave deposits, and the fancy word for these cave deposits are speleothems.

Writing nuclear equations for alpha, beta, and gamma decay. For example, one kilogram is about two pounds. So t equals 2.

They all have some probability of the decaying. Studying for a test? So we started with this.

And we'll do that in the next video. Atomic number, atomic mass, and isotopes.

Let's say I have a bunch of, let's say these are all atoms. I'm carbon dating crash course making up this compound. And normally when we have any small amount of any element, we really have huge amounts of atoms of that element. Those are the speleothems that are coming from the top of the cave.

You get the idea. And we've talked about moles and, you know, one gram of carbon I'm sorry, 12 grams-- 12 grams of carbon has one mole of carbon in it. You know it has a two-year half-life.

But that's not what's relevant here.
