About This Product
In class, the two oxygen atoms are identified first, then the model is used to discuss how they share electrons and why two shared pairs make a double bond. It gives teachers a visual reason for writing elemental oxygen as O2 rather than as an isolated atom, and supports work on valence electrons and Lewis structures.
Frequently Asked Questions
Q1. Why is the bond in O2 drawn as a double bond? In the standard introductory Lewis picture, each oxygen atom has six valence electrons and the two atoms share two pairs of electrons, which is written as O=O.
