For the following, draw correct Lewis structures showing any formal charges and resonance structures on this sheet. For each molecule, give the geometry, shape and hybridization of the central atom in the molecule and whether the molecule is polar or non-polar (has a dipole moment). Fill in the table with these values. In your diagram, show one of the bond angles between bonded atoms (you choose which one). Put the hond angle in the answer table as well. (8 points...
