1. Lodine, l₂, dissolves in an aqueous solution of iodide ion, I^-, to give the triiodide ion, I₃^-. This triiodide ion, I₃^-, consists of one iodine atom bonded to two others.

Write the Lewis formula for the I₃^- ion.

Identify the bonding pairs and lone pairs in the Lewis electron-dot formula of I₃^-ion.

Predict the electron arrangement and the shape or geometry of the I₃^- ion using the VSEPR model. Draw the VSEPR sketch

What hybrid orbitals are expected for the central atom in the I₃^- ion

Describe the bonding in the I₃^- ion, using valence bond description and give the valence bond sketch of the I₃^- ion.

2. Distinguish between an acidic, basic and an amphoteric oxide. Is PbO₂ an acidic, basic or amphoteric oxide?.

3. Use Lewis symbols to show the reaction of atoms to form a covalent molecule H₂O. Write the Lewis formula for H₂O assuming octet rule holds For atoms. Identify the bonding pairs and lone pairs in the Lewis electron-dot formula of H₂O.

4. Predict the electron arrangement and the shape or geometry of the H₂O molecule using the VSEPR model. Draw the VSEPR sketch. State the bond angle you would expect to see on the central atom based on the simple VSEPR sketch. Would you expect the bond angles to be greater or less than this? Would you expect a zero or a nonzero dipole moment for the H₂O molecule. Explain your answer.
