Beryllium and Chlorine Lewis Structures

Dr. B explains how to draw the Lewis structure for Beryllium Chloride. Beryllium has 2 valence electrons, and each Chlorine has 7, totaling 16 valence electrons. Beryllium is placed in the center with Chlorines on either side. After drawing the structure, Dr. B checks for octets and explains that Beryllium is an exception, not needing 8 electrons. To confirm the structure, formal charges are calculated, showing all atoms have a formal charge of 0, indicating the best structure.
