The corona is the outermost layer of the Sun's atmosphere and is one of the hottest regions.

Its outermost shell is 1s.

Well, what's the outermost shell?

And this is the outermost shell.

This is your outermost shell right here.

Valence electrons are just the outermost electrons.

Valence electrons, or electrons in the outermost shell?

Where you're only drawing the outermost, valence electrons.

Potassium has one electron in its outermost shell.

Well it has seven in its outermost shell.

These all have two atoms in its outermost shell.

Remember, the outermost shell is the period you're in.

Carbon, I have four electrons in my outermost shell.

Its outermost shell won't be the fourth shell anymore.

But in terms of their outermost shell, only two electrons.

They want to have eight electrons in their outermost shell.

So this one also has two electrons in its outermost shell.

All of these guys have two electrons in their outermost shell.

Or it has the same number of electrons in its outermost shell.

And the gems are always the outermost aspects of our interviewee's personality.

In the case of iron, how many electrons in the outermost shell?

Everything in this first group has one electron in its outermost shell.

In the case of lithium, you have one electron in your outermost shell, right?

So all of these are going to have two electrons in their outermost shell.

In the case of these, the outermost electrons are going to be 4s2, right?

little bit about them in a second have eight electrons in the outermost shell.

Let's say you have stuff like chlorine, that has seven electrons in its outermost shell.

And what's the easiest way for potassium to have eight electrons in its outermost shell?

In the outermost corner were found traces of fruit drops and particles of powdered sugar.

Overlaid with economic regions, fiscal regions, administrative regions.

This is because an atom of silicon has four electrons in its outermost or valence shell.

I have two electrons in my outermost shell, so iron I could just do like this.

Well, it turns out that all atoms want to have eight electrons in their outermost shell.

In order for them to get to the magic number eight in their outermost shell the easiest way for them to do it is just to get rid of that one valence electron they have in their outermost shell.

Fornjot, or Saturn XLII (provisional designation S 2004 S 8), is the outermost natural satellite of Saturn.

Every cell in your body is separated from those around it by its outermost layer, its membrane.

Now what does this tell me about, you know, this one has one electron in its outermost shell.

Well, if it lost that one electron, then it will have eight electrons in its outermost shell, right?

This column, right here, which we learned were the alkali metals, this has one electron in its outermost shell.

We can view it that way, in their outermost shell, but then they go and backfill the d shell.

But through experimentation, it has been well established that atoms want to have eight electrons in their outermost shell.

The reason why I'm doing all of this is to figure out how many electrons you have in the outermost shell.

It must be something about the atoms in the outermost shell, when you have eight, they resonate well with each other.
