To draw the Lewis structure for polyatomic ions, follow these steps:
- Determine the total number of valence electrons for the ion.
- Place the least electronegative atom in the center and connect the other atoms to it with single bonds.
- Distribute the remaining electrons as lone pairs around each atom to fulfill the octet rule, except for hydrogen which follows the duet rule.
- If there are still electrons left after satisfying the octet (or duet) rule for each atom, place them on the central atom as lone pairs or multiple bonds to fulfill the octet rule for the central atom.
- If the ion has a charge, add or subtract electrons accordingly to match the overall charge of the ion.
- Verify that all atoms have a complete octet (or duet for hydrogen) and that the total number of electrons matches the charge of the ion.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
