Graphical presentation of a water molecule: The red oxygen atom is much larger than the two connected hydrogen atoms. The angle between the two hydrogen atoms is 104 degrees, the deviation from the ideal tetrahedral angle of 109.5 degrees is explained by the large amount of space required by the two free electron pairs. Information and ideas: Introduces students to the language of chemists: What is an atom? What is a chemical compound? What is a molecule?
