Why can some Period 3 elements not follow the octet rule? For example, P, S, Cl

I believe this has to do with the larger size of period 3 elements and how they are able to accommodate more bonds.

Period 3 elements have access to the 3d orbital even though they fill the 3p orbital first. Electrons in the d orbital still can function as valence electrons. This allows them to form more bonds/have more lone pairs than the octet rule would typically allow.
