Homework Help: CHEM AP please help!!

Why does the octet rule not hold for many compounds containing elements in the third row of the periodic table and beyond? (Select all that apply.)

1. Atoms of elements in the third period are less subject to destabilization from additional electron-electron repulsions.
2. Atoms of elements in the third period contain f orbitals that are relatively close in energy to 3p and 3d orbitals and provide an allowed energy state for extra electrons.
3. Atoms of elements in the third period have the space and available orbitals to accommodate extra electrons.
4. The third shell contains d orbitals that are relatively close in energy to 3s and 3p orbitals and provide an allowed energy state for extra electrons.

I put 1,3 1,2,3 3,2 and 4,1 1,2,3,4 just 1 just 2 just 3 just 4 but none of those combos worked!
