Expanded Octets

[Armani Dodson 1A]

How to elements in the 3rd period like Sulfur have an expanded octet? I know the 3d orbital is part of it, but how is this possible if 3d is I the 4th period??

The reason the Octet rule can be 'expanded' for certain elements is through utilizing the d-orbitals that are found in the third principal energy level of the element.

I thought that any element after Si could have an expanded octet?

[Daniel_Callos_4I]

Éléments with empty d orbitals can fill their d orbitals for the purposes of bonding, thus resulting in an expanded octet of 10 or even 12 electrons.

Up to how many electrons can an atom hold when using the expanded octet rule?
