Teacher Preparation: See individual resources. This unit supports students’ understanding of Recognize that physical properties are related to intermolecular forces.Identify the intermolecular forces present in chemical substances.Manipulate models to demonstrate molecular orientations giving rise to London dispersion forces, dipole-dipole forces and hydrogen bonds.Rank molecules in order of increasing strength of van der Waals forces, given a set of structural formulas for several compounds.Describe the unique behaviors of water molecules, and why they are important.Explain the meaning of the following: cohesion, adhesion, surface tension, and capillary action.Relate the shape of a molecule and the relative electronegativity values of its constituent atoms to the polarity of the molecule.Make the correlation between geometry, nonbonding pairs and molecular shape.Understand that the molecular shape names are descriptions of the actual shape.Describe the implications of electron pair repulsions on molecular shape.Conceptualize the impact of one electron pair domain acting upon another, and understand how those interactions result in the molecular geometries predicted by VSEPR theory.Identify that different metals have different properties.Visualize “free-moving electrons” in metallic bonding.Name and write the formulas for binary and ternary ionic compounds.Explain the purposes of superscripts and subscripts in chemical formulas.Explain why different quantities of ions combine to make different compounds.Explain why stable, neutral ionic compounds are formed from cations and anions.Predict the molecular shape of a covalent molecule based upon its Lewis dot structure.Create a Lewis dot structure for an atom, covalent compound, and ionic compound.Determine the number of valence electrons for an atom.Compare and contrast the basic structure of ionic and molecular compounds.List some properties of ionic, covalent, and metallic bonds.Predict the number of atoms needed in a molecular formula.Identify compounds as ionic, covalent, or metallic based on their chemical formula.Use electronegativity values to predict whether an ionic or covalent bond is most likely to form.Distinguish between the locations of metal atoms versus non-metal atoms on the periodic table.We constructed a unit plan using AACT resources that is designed to teach Chemical Bonding to your students.īy the end of this unit, students should be able to The AACT high school classroom resource library has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. ![]()
