Uen: Grouping Bonds
Students will group a selection of electron dot structures and determine similarities and differences between covalent and ionic bonding.
McMaster University
Mc Master University: Covalent Bonding
Slides 5 through 8 in this presentation from the McMaster University explain covalent bonding.
Other
Organic Chemistry: Lewis/kekule Structures
This slide presentation contains a few slides that will be useful for students learning to write Lewis structures. A discussion of multiple bonds is included, and clear examples are shown.

Middle School Chemistry: Represent Bonding With Lewis Dot Diagrams
Learners draw and interpret Lewis dot diagrams for individual atoms and both covalent and ionic compounds.
Science Education Resource Center at Carleton College
Serc: Loopy Lewis Dot Diagrams
Students will use colored fruit loops to organize valence electrons to develop and master the basics of Lewis Dot diagrams. They will develop processing and critical thinking skills and also master a model of bonding.
McMaster University
