Molecule # 1 ТеОз- Draw the Lewis Structure below Calculate the number of valence electrons Draw the three-dimensional structure of the molecule using the "wedge and dash" notation. The molecular geometry is: This molecule is polar nonpolar (Circle your choice.) Our logic for this choice is: The formal charge on the central Te atom is on the terminal O atom is The hybridization of Te is Estimate O-Te-O bond angle Molecule # 2 CIF.+ Calculate the number of valence electrons Draw the Lewis Structure below Draw the three-dimensional structure of the molecule using the "wedge and dash" notation.

Write the Lewis structure for I3- on your paper.  Include formal charges on all atoms.  Include all resonance structures if there is resonance in this ion. Answer the following questions for the central atom in the species

provide th following information for NCl3 and HCN including the Lewis structure and 3D sketch

Why is it less clear to see the electrons on HBrO2 molecular electron geometry than it is on something like H2O? I know there should be 20 electrons on HBrO2, but this leads me to an incorrect drawing. And with the correct drawing, I don't see where all the electrons are. It seems like there's only 10 total. What am I missing here?

Part A) Draw the following lewis structures and give the formal charges for the atoms as well as the number of valence electrons I2 Part B)According to VSEPR theory, why are bonds and lone pairs spaced as far apart as possible? Part C)Why can we ignore the disposition of the lone pairs on terminal atoms? Part D)What are the bond angles for a molecule having an octahedral electronic geometry with two lone pairs and four bonds on the central atom?
