However, having run this lab a few times, the following types of candy always work well: Pinterest has loads of ideas on the kinds of candy that are appropriate for this activity. Recognize from a Lewis structure the molecular geometry of a compound.Give examples of molecules which have each geometric shape.Identify molecules which show resonance.Name the different geometric shapes using a 2D or 3D image.Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.īy the end of this lesson, students should be able to: Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms. These molecules can then be used to determine the geometry of the compounds.Īs well as learning the names for each 3D shape, students should also start to see how their two-dimensional drawings actually exist in three dimensions. This practical activity allows students to practice drawing Lewis structures for a number of different covalent compounds in order to use them to assemble their candy molecules. The molecular geometry main shapes are tetrahedral, trigonal planar, trigonal pyramidal, bent, and linear and are named by measuring the bond angles between the central atom and another atom bonded to it. The valence shell electron pair repulsion (VSEPR) theory (or “VESPER” for short) is how the geometry of a molecule is determined around a central atom.
