Valence shell expansion refers to the phenomenon where elements from the third row and below on the Periodic Table can exceed the octet rule by utilizing d orbitals in addition to s and p orbitals to accommodate more than eight electrons in their valence shell. This allows these elements to form more than the usual number of bonds and have expanded valence shells.
