Activity 1: Drawing Lewis Structures

1. Determine the total number of valence electrons; for polyatomic ions remember to adjust for charge.

2. Arrange atoms in a skeleton structure and connect them with single bonds.

3. Complete octets of the terminal atoms (remember H atoms can only accommodate 2 electrons).

4. If not all of the valence electrons have been used place any extra electrons on the central atom.

5. If the central atom does not have an octet, use lone pairs from terminal atoms to form multiple bonds.
