Examples of atoms that have more than 8 electrons in shell

[MatsNorway]

Hi

So we are about to learn about the octet rule. However once you get to higher shells you can have more than eight in the "shells" or orbit? But i have not been able to find a good example of how that works or happens. Does it have a specific name? I assume we are talking about say several fluorines conntected to a bigger atom. Sharing the electrons in some way.

Links on videos that explains it is very welcome.

I don't understand this question.

First of all, what exactly do you mean by a "shell"? I ask this because I don't know why you can't just look up the periodic table and figure out the atoms that have more than 8 electrons in an orbital.

The s, p, d, f, etc... can have 2, 6, 10, 14, etc.. electrons, respectively. So already we know that an orbital CAN have more than 8 electrons. So why not look at atoms with a full d-orbital, for example? Shouldn't this be an atom that has more than 8 electrons in a "shell"?

Does it have a specific name?

Hypervalence?

Correct. Found it after much googling. I first thought it was super octet but that seems to be the opposite.

What i have found so far.
https://en.wikipedia.org/wiki/Hypervalent_molecule
https://chemistry.stackexchange.com...electrons-if-not-why-is-8-the-limit/5242#5242

In my course we do not go this far, what i was curious about is how you figure out how many of a atom can mix with another. And it led me down this rabbit hole, I started of just counting the electrons thinking they need to match up to become a molecule where one or both have 8 valence electrons. Before today i did not know what valence electrons was. Now i have some super basic idea.

If anyone have a super basic intro video to that kind of "math" or how to do video that would be appreciated ofc. Hell.. anything you think is quality on the topic is welcome. I devour good documentaries.
