Sample Learning Goals Predict bond polarity using electronegativity values Indicate polarity with …
Sample Learning Goals Predict bond polarity using electronegativity values Indicate polarity with a polar arrow or partial charges Rank bonds in order of polarity Predict molecular polarity using bond polarity and molecular shape
Sample Learning Goals Recognize that molecule shape is due to repulsions between …
Sample Learning Goals Recognize that molecule shape is due to repulsions between atoms. Recognize that bonds are not fixed in place, but can rotate around in response to repulsions.
Sample Learning Goals Recognize that molecule geometry is due to repulsions between …
Sample Learning Goals Recognize that molecule geometry is due to repulsions between electron groups. Recognize the difference between electron and molecular geometry. Name molecule and electron geometries for molecules with up to six electron groups surrounding a central atom. Compare bond angle predictions from the VSEPR-based model to real molecules. Describe how lone pairs affect bond angles in real molecules.
In this lesson, students will define chemical bond, ionic bonding and properties …
In this lesson, students will define chemical bond, ionic bonding and properties of ionic compounds, and covalent bonding and properties of covalent compounds. Students will also explain polarity in bonds, predict bond types, and define metallic bonding.
Sample Learning Goals Describe a molecular model for solids, liquids, and gases. …
Sample Learning Goals Describe a molecular model for solids, liquids, and gases. Extend this model to phase changes. Describe how heating or cooling changes the behavior of the molecules. Describe how changing the volume can affect temperature, pressure, and state. Relate a pressure-temperature diagram to the behavior of molecules. Interpret graphs of interatomic potential. Describe how forces on atoms relate to the interaction potential. Describe the physical meaning of the parameters in the Lennard-Jones potential, and how this relates to the molecule behavior.
