This video shows you how to draw the lewis struture for AsCl5. Exceptions to the Octet Rule - ThoughtCo Sb is a bigger atom than As, so it is not surprising that it finds it easier to accommodate six chlorine atoms round it. A similar reason has been given for other facets of the behaviour of these elements, such as the difficulty in making the perbromate ion. The resonance structure of arsenic pentachloride is same as its shape. The structure of the solid was finally determined in 2001. Molecular geometry, also known as the molecular structure, is the three-dimensional structure or arrangement of atoms in a molecule.
