Use the References to access important values if needed for this question. Please note that "geometry" refers to the molecular or ionic geometry. In the VSEPR model, the geometry of the regions defined by the electron pairs in the valence shell of an atom is called the electron-pair geometry. A. The Lewis diagram for BeBr2 is: The electron-pair geometry around the Be atom in BeBr2 is There are unshared pair(s) around the central atom, so the geometry of the BeBr2 molecule is B. The Lewis diagram for AlCl3 is: The electron-pair geometry around the Al atom in AlCl3 is There are unshared pair(s) around the central atom, so the geometry of tha airi malenitis is
