Atomic number

And so here we have definitions of that are provided by Janiyah.

Important relationships, so A equals Z plus N.

Here A is mass number, Z is atomic number, and N is neutron count.

All right, so for neutral atoms, electrons equal protons.

For an ion, the charge equals protons minus electrons.

Now let's get into it.

Welcome, everyone, to episode number 95, the atomic number of, oh, I can't wait for this one, americium, americium.

We just renamed that.

No, we didn't.

Now they just got bored.

Which is classier, but just doesn't have quite the scale.

They got less creative as the atomic numbers went up when it came to naming them, the higher up you went.

Anyway, two American expats in Geneva, one from New York City and one from somewhere in the middle, are doing episode 95, the atomic number of americium.

Yep.

But I mean, Z star is way more complex than just looking at the atomic number, right? Like you can't just count the protons and call it a day.

No, definitely not.

Because the inner core electrons, they physically shield the valence shell from feeling the full electrostatic force of the protons in the nucleus.

Shielding.

Okay.

So the foundational equation for this from the source is Z star equals Z minus S, right? Where S is the shielding constant.

You got it.
