Lewis structures, also known as electron dot structures or Lewis dot diagrams, are used to represent the bonding between atoms in a molecule. They show the valence electrons and help chemists predict ...

- Select the best Lewis structure from multiple possibilities based on formal charges. - Draw resonance structures and calculate fractional bond order. - Define the following terms: Formal charge, ...

Instead of trying to remember lots of different dot and cross diagrams, it may help to understand how to draw them.
