Expansion for 3s?

[samanthaywu]

Does octet expansion apply to atoms with 3s valence electrons? I'm wondering if 3s energy is high enough for electrons to expand and occupy the 3d orbital.

If i am understadning your question correctly, no. Only atoms in the p-block from n=3 down can have an expanded octet, so I think for atoms that only have the 3s orbitals available to them they cannot form an expanded octet.

Hi, I'm pretty sure that atoms with 3s valence e- can't expand into 3d for ground state. I think the expanded octet concept mostly applies to the p-orbital if I'm not wrong.

No, it would need to have a d-orbital and atoms in 3s don't use the d-orbital.

No, atoms in 3s do not use the d orbital.
