A set of Flash-based, interactive tools for students to construct Lewis structures for electron deficient, octet rule obeying and hypervalent MLx molecules and ions (x = 2 - 6).
The user chooses the number of electrons and bond type (single, double or triple) and is steered towards the correct stucture.
For cases where resonance structures are possible, the user must construct each form to complete the puzzle.
A student should be able to draw Lewis structures for electron deficient, octet rule obeying and hypervalent molecules.
A student should be able to construct resonance structures where appropriate.
Self-learning tools for students to back up lectures.
