Period 3

Postby Trent Yamamoto 2J » Sun Nov 03, 2019 11:24 pm

Why can atoms in the third period or higher accommodate more than 8 valence electrons?

I am not 100% sure but I think it has something to do with the fact that these elements are nonmetals with the presence of a d orbital. This somehow allows then to fill and sometimes expand their octets to stabilize the structure.

Atoms in that period have empty 3d-orbitals to accommodate for the expanded octet.
