Introduction to Chemical Bonding. Objectives:. Define . chemical bond.. Explain why most atoms form chemical bonds.. Describe ionic and covalent bonding.. Explain why most chemical bonding is neither purely covalent nor purely ionic.. The ability of an atom in a molecule to attract shared electrons to itself.. Linus Pauling. 1901 - 1994. Table of Electronegativities. Higher electronegativity. Electronegativity differences determine bond type.. Unit 16. Shapes and Electrical Properties of Molecular Compounds. VSEPR . Theory (4.12). Electronegativity (4.7). Identification of Compounds as Polar or . Nonpolar. (4.13). VSEPR Theory (4.12). The geometry of molecules is important in determining some of their properties. By Myre and William. Gasses. Gasses are particles that float from earth to the . atmosphere and its particles go around to fill every place in a container and when the . they are open they will go to every space around.. C483 Spring 2013. Questions. T/F . The Golgi apparatus consists of flattened, fluid-filled, membranous sacs and is responsible for chemical modification and sorting of some biomolecules. .. T/F . The endoplasmic reticulum is the major site of RNA synthesis and the site of assembly of ribosomes. . Describe . ionic bonding. in 1 complete sentence.. Describe . covalent bonding. in 1 complete sentence.. Polar. Nonpolar. nonpolar covalent bond. :. nonpolar covalent bond. : . atoms with equal pull (similar electronegativity) so bonding . Learning Goals …. … . identify symmetry . in a molecule. … determine overall polarity of a molecule . Determining Molecular Polarity. Overall Polarity of a Molecule depends . on:. dipole . Vocabulary. Soluble/miscible- will dissolve in a solvent. Insoluble/immiscible- will not dissolve in a solvent. ~Both of these terms require a solvent. For example vitamin A is a fat soluble vitamin, meaning it will dissolve in oils (fat). How does your sense of smell work? . If a molecule fits into a receptor site in your nose, should all things smell? Why do you think you don’t smell the molecules of O. 2. , N. 2. , or CO. 2. in the air? .
