Do you understand?
Yeah
Okay
We know that argon has 8 electrons, and thus has little to no reactivity
Do you agree
Yeah
Okay
We know that by using quantum physics, we can calculate the half life of potassium 40, an isotope of potassium, to be 1.25 billion years
Do you agree?
I did not know that
Are you going to continue?
Yes
Okay
We know that K-40, potassium 40, decays into two atoms
since it’s radioactive
Argon 40, and Calcium 39
We know that 11% is argon 40, and 89% is Ca 39
Isn't it Ca-40?
@NickC64 sorry I had to go, I'm at work)
No
One of the neutrons turns into an electron
Pretty sure
Maybe proton
Alright
And if we have some sort of volcanic eruption, the lava is illiquid
Liquid**
That means that any argon 40 in there, since it’s low reactivity, is free to move out of the lava
Perhaps an error in the wikipedia article then, it says Ca-40
It’s probably an error
@PhumoZTYPE anyway
Because of this, we know that any argon 40 in the rock must have came from the parent element
Which is K-40
Yup
Good
Now, we can get to the fun part
It would be easier if I could send pictures
Yeah I guess
We can take our original equation, N_0 times e^-kt = N(t)
Checked, it's Ca-40 from beta decay of K-40
I’ll have to read up on that then
