The octet rule applies to the elements of the main group but not to transition metals. Explain.

The octet rule does not apply to transition metals because they have a greater metallic character that can accept more electrons.

The octet rule does not apply to transition metals because they have a large molar mass that can expand of their valence orbital.

The octet rule does not apply to transition metals because they have partially filled d orbitals that can accommodate additional electrons.

The octet rule does not apply to transition metals because they more orbitals that produces more space for electrons.
