For each of the following molecules or polyatomic ions, complete the following:
- Write the formula on a piece of paper.
- Calculate the total number of valence electrons and enter it in the blank provided.
- Neatly draw the Lewis structure on the paper. (If there are resonance structures, include them all.)
- Determine the molecular geometry and enter it in the blank provided.
- Based on the molecular geometry, enter the optimal bond angle. (e.g. 90, 109.5, 120, 180)
- Use electronegativity values to determine if the bonds are polar or nonpolar. (Enter "polar" or "nonpolar" in the blanks provided.)
- If the bonds are polar, draw a modified arrow ( +----> ) above each bond in the Lewis struture, pointing to the more electronegative element.
- Determine if the overall molecule is polar or nonpolar. (Enter "polar" or "nonpolar" in the blank provided.
