Like NH3, this molecule is pyramidal. So it is essential to get the optical thickness of water “just right”: enough to support life and ensure the validity of model systems, but not so much that it masks the molecular signatures of interest. As has 5 valence, O each has 6 for a total of 18, plus an extra electron for the negative charge, totals 24. A 2 dimensional shape such as a circle is NOT a solid shape, while a sphere is. ; For the AsO 3 3-Lewis structure there are a total of 26 valence electrons available.
