4? sPUctures for atoms beyond the period on, d orbital UP that is that, from the third ly be available, not just 2 s electrons and 6 p electrons for a completed We will learn how to write for let's practice with second period elements. Note even for neither Be nor B have sufficient valence electrons. ntly not viable. wis structures for these "extended shell" structures, but first here the octet rule would not apply, 3. Sketch out the Lewis structures for the following, then determine the number of regions of electron density around the central atom of each molecule.

Assume each region of electron density is trying to maximize its distance from the other areas. All areas are included in the determination of these geometri that involve unshared pairs of electrons. We will call this shape the "electronic geometry". Write the name of the electronic geometry of each of the molecules in the table above es, even the areas 304
