To learn how to draw a Lewis Dot Diagram for a molecule which has a double or triple bond.
To learn how to represent and resonance structures in Lewis Dot Diagrams.
This packet has definitions, a video with examples for Lewis Dot Structures with double and triple bonds, and a video for resonance structures.

Single Bond: "A covalent bond between two atoms that is formed by one bonding pair of electrons." G-14
Double Bond: "A multiple covalent bond between two atoms that is formed by two bonding electron pairs." G-5
Triple Bond: "A multiple covalent bond between two atoms that is formed by three bonding pairs of electrons." G-15
Multiple Covalent Bond: "more than one bond between atoms, formed by the sharing of more than one electron from each atom. Can be either a double bond or triple bond." G-10
Resonance Structures: "Two or more equally correct dot representations of the same molecule; representation is the actual structure of the molecule." G-13
