Sulfur can have an expanded octet because it is in Row 3 of the periodic table, meaning that the quantum number n is equal to 3. When n=3, l can be 0, 1, or 2 according to the rules for quantum numbers. This means that elements in Row 3 have the S, P, and D subshells available to them to hold electrons.

Web2 days ago · Sulfur can expand its octet and can accommodate up to 12 electrons because of which, it does not follow the octet rule. Sulfur can do so as it has access to energetic 3d-subshell for bonding. As there is a small energy difference between 3p and 3d shells, with the help of a little excitation, an unpaired electron can move from the 3p shell …
