Expanded octets

Postby OrAmar-1L » Mon Jun 04, 2018 8:45 pm

Which elements can expand their octets, why can they do this, and how many electrons can they take?

Elements period 3 and below can expand their octets because they have a d-orbital and they can play with those electrons if necessary. They should be able to take an extra 10 electrons, the number of electrons in the d orbital.

Any element below N=3 can have an expanded octet.

The most common ones are Sulfur and Phosphorous.

What do you mean by "an extra ten electrons?" I thought that the total amount of electrons an expanded octet could hold was twelve?

Only elements after period 3. For instance, elements in period 3 has unoccupied d orbitals which enable them to expand their electro clouds.

Elements after period 3 can have an expanded octet because of the additional d orbital they have. Typically, Phosphorus or Sulfur are the elements that do expand their octet.
