Structure & Bonding

Content Videos (Lectures and animations to supplement lessons):

Interactives (Online activities for student interaction & practice with content):

Molecular Shapes Basics Simulation (students explore molecule shapes by building molecules in 3D! Find out how a molecule’s shape changes as you add atoms to a molecule)
Molecular Shapes Advanced Simulation (students explore molecule shapes by building molecules in 3D! How does molecule shape change with different numbers of bonds and electron pairs? Find out by adding single, double or triple bonds and lone pairs to the central atom. Then, compare the model to real molecules!)
Molecule Polarity Simulation (students ask when is a molecule polar? Change the electronegativity of atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how shape affects polarity. See how it works for real molecules in 3D)
Lewis Dot Diagrams of Covalent Compounds (In this interactive and animated object, students distribute the valence electrons in simple covalent molecules with one central atom. Six rules are followed to show the bonding and nonbonding electrons in Lewis dot structures. The process is well illustrated with eight worked examples and two interactive practice problems)
Bonding (students use this interactive activity to learn about chemical bonding. Click on the tabs to see animations of how pairs of elements in the periodic table bond together. Learn about the role of valence shell electrons and attractive forces in three types of chemical bonds: covalent, ionic, and metallic)
