Oxygen is -2 (by assignment) and As is +5 The convention is to assign -2 to oxygen when it appears in any compound (except for H_2O_2 where it is -1). And this pattern is represented in the resonance structures too. 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. The Lewis diagram for PCl3 is as follows: The four electron pairs arrange themselves tetrahedrally, but the lone electron pair is not considered in describing the molecular shape.
