Re: Expanded Octets
Common elements that can have an expanded octet are sulfur, phosphorous, silicon and chlorine. They can have more than an octet because they have d- orbitals that can hold electrons. These d-orbitals have higher energy than 4s- orbitals so those electrons are used for bonding.

Re: Expanded Octets
Any element on or below period 3 of the periodic table can have an expanded octet because these elements have d orbitals that can hold more electrons.

Re: Expanded Octets
Elements that would be considered to have an expanded octet are those in period 3 and beyond because these specific elements can/are able to hold electrons in the d-orbital shell.

Re: Expanded Octets
Elements that have a d orbital can have expanded octets. However, a few elements on the right side of period 3 can expand with the extra electrons. S and Cl are common examples of central atoms with more than 8 electrons.

Re: Expanded Octets
Any element in period 3 or below can have expanded octets as they can expand into the d-orbitals.
