Unformatted text preview: priate. Be sure to show all lone pairs, including those on outer atoms, and be sure to label any non‐zero formal charges on individual atoms. Then, identify the electron‐domain geometry, the molecular geometry, and all approximate bond angles found in the molecule. +2 correct 3‐D structure; +1 each correct box; 1 missing lone pairs on atoms 6
