Valence Shell electrons

Postby Lucy Wang 2J » Sun Nov 08, 2020 9:51 pm

So my understanding is that valence shells must have 8 electrons. And these are represented by the s2p6. However, what does the d and f orbital represent then? Do these also fill valence shells?

Hi Lucy!
The d and f orbitals would be used for atoms that have higher numbers of electrons, like Silver or berkelium respectively. Typically, when doing octet rule, we don't look at these orbitals--> we use the octet rule for main group elements only, and not transition metals or otherwise. But, these elements would use fill their electrons in the d orbital, and the lanthanides + actinides would fill electrons in f orbital as well.

I believe that no matter how many electrons are in an atoms d and f orbitals, that does not account for how many electrons are in the atoms valence shell, the outermost valence shell is always consisting of the s and p orbitals. So for example, zinc has only 2 valence electrons, because those are the ones it has in the 4s-orbital, which is how full its valence shell is.
*(keep in mind the idea of filling order as well)
