OPRFHS-‐NGSS Curriculum Alignment Chemistry 575 Unit: Covalent Bonding (Ch 8) and Molecular Naming (Ch 9.3)
Updated 1/8/2013 10:23 AM
Big Idea(s)/ Unifying Q(s):
Is Covalent bonding really “sharing”? Sharing what?
DCI-‐NGSS • Structure and Properties of Matter (PS1.A) • Types of Interactions (PS2.B)
SEP-‐NGSS Developing and using models (2), Engaging in argument from evidence (7) CCC-‐NGSS Cause and effect (2), Systems and system models (4), Structure and Function (6)
Molecular Compounds 8.1 The Nature of Covalent Bonding 8.2
Bonding Theories 8.3 Polar Bonds and Molecules 8.4 Naming and Writing Formulas for Molecular Compounds 9.3
• covalent bond • molecule • diatomic molecule • molecular compound • molecular formula
• single covalent bond • structural formula • unshared pair • double covalent bond • triple covalent bond • coordinate covalent
bond • polyatomic ion • bond dissociation
energy
• VSEPR Theory • Common molecular
shapes: Linear triatomic, trigonal planer, bent triatomic, pyramidal, tetrahedral.
• nonpolar covalent bond • polar covalent bond • polar bond • polar molecule • dipole • van der Waals forces • dipole interactions • dispersion forces • hydrogen bond
• Prefixes for binary molecular compounds (table 9.4 pg 269)
DCI, EO and OP Objectives Student Learning Targets (coded to DCI, EO or OPRF Objectives) 1. Students will construct models showing that stable forms of matter are those with minimum magnetic and electrical field energy. (HS.PS-‐SPMa) 2. Students will construct various types of models showing that energy is needed to take molecules apart and that energy is released when the atoms come together to form new molecules. (HS.PS-‐SPMb) 3. Students will construct arguments for which type of atomic and molecular representation best explains a given property of matter. (HS.PS-‐SPMd) 4. Students will be able to describe characteristics of a molecular compound and how a covalent bond forms at an atomic level. (EOC 22) 5. Students will be able to name and write formulas for compounds. (EOC 4)
1a., 2b. I can explain that a stable molecule has less energy (amount known as binding energy) than the same set of atoms separated. (HS.PS-‐SPMa, HS.PS-‐SPMb) 3a. I can describe attraction and repulsion at the atomic scale to explain structure, properties, and transformations of matter. (HS.PS-‐SPMd) 4a. I can identify a compound as covalently bonded by the types of elements in the compound. (EOC 2201) 4b. I can describe how a covalent bond forms at an atomic level (sharing electrons, multiple bonds, octet rule). (EOC 2202) 4c. I can describe the general characteristics of a molecular compound (melting and boiling points as they relate to intermolecular forces). (EOC 2203) 4d. I can draw an electron dot diagrams (Lewis dot diagram) and structural formulas. (EOC 2204) 5a. I can use naming rules to name or write the formula for molecular compounds. (EOC 402) 6a. I can identify molecules as polar, non-‐polar. 6b. I can use polarity to predict melting points. 6c. I can use polarity to predict solubility and the speed of molecules using chromatography
