Expanded Valence Shells

Postby Nikki Razal 1L » Sun Nov 03, 2019 6:42 pm

Why can only some elements in the 3rd period have an expanded valence shell?

I thought that all elements in or past the third period can have expanded octets because they have an empty d orbital where the extra electron can go.

I'm pretty sure that it is all of the elements in or past the third period can have expanded valence shells.

Atoms within the third period or past that can have expanded valence shells for electrons, since they have the d-orbitals.

Elements past the third period can have expanded valence shells due to the presence of a d-orbital.

Theoretically speaking, all atoms in the 3rd energy level can break the octet rule because of their unused 3d orbitals that can accommodate extra electrons; however, in nature, only a few atoms consistently do this.

Elements with d orbitals (period 3 and beyond), can have expanded valence shells.
