IB Topics 4 amp 14 Text Ch 8 all except sections 45 amp 8 Ch 91 amp 95 Ch 101107 My Name is Bond Chemical Bond PART 5 Giant Covalent Structures Metallic Bonding amp Physical Properties. 92B is applicable to bonding at services and in part states Bonding jumpers meeting the other requirements of this article Article 250 shall be used around concentric or eccentric knockouts that are punched or otherwise formed so as to impair the ele and . Electronegativity. Presented by . Leticia Bonita Prince. Newcastle University 4. th. Year . MChem. Student. Aims of Today. Increase your understanding of bonding and electronegativity. Increase your spatial skills and awareness using software designed by the CCDC. Molecular Geometry. Ch. 6 Sections 1-4 Review. In general, what determines whether atoms will form chemical bonds?. Atoms will form a chemical bond if their potential energy is lowered in doing so.. Describe the difference between ionic and covalent bonding.. Introduction to Chemical Bonding. 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.. Co = Together. The Octet Rule. The octet rule says that all atoms want to have eight valence electrons, like the noble gases.. One way that atoms can follow the octet rule is by giving and taking electrons… ionic bonding. What types of things bond together?. Think-pair-share with your neighbor all of the things that bond together.. Share with entire class. What would happen if the bonds didn’t hold or were weak?. Bonding. Molecular Shapes. VSEPR Theory. From a correct Lewis structure, we can get to the 3-D shape using this theory.. VSEPR stands for . v. alence . s. hell . e. lectron . p. air . r. epulsion.. The theory is based on the idea that e- pairs want to get as far away from each other as possible!. Epigenesis. Marshmallow Experiment. Walter . Mischel. Stanford University. Imprinting. Konrad. Lorenz. Imprinting. Imprinting. Imprinting. Imprinting. Imprinting. John . Bowlby. Attachment . Theory. Covalent bonding. Ionic bonding. Ionic Bonding. Bonding as you’ve never imagined it. http://www.youtube.com/watch?v=BCYrNU-7SfA. Objectives. To consider the features of ionic and covalent bonds, and the compounds they make. Chemical bonding. Chemical Bonding. Diamond. Silicon dioxide. Graphite. Ionic Bond / metallic bond / covalent bond. Nature of the bond. Physical properties . Melting point / boiling point. Electrical conductivity. Electrons are transferred from an atom of low electronegativity to one of high electronegativity. Anion (-) and cation ( ) formed. Opposite charges attract – called an . electrostatic force. Formula Unit. Text:. Ch 8 (all except sections 4,5 & 8). Ch 9.1 & 9.5. Ch 10.1-10.7. My Name is Bond. Chemical Bond. PART 4: . Intermolecular Forces. Intermolecular Forces. Dipole-Dipole . Hydrogen Bonding . Covalent Bonding. A . chemical bond . is the force that holds two atoms together and makes them function as a unit. Atoms form bonds to become most stable and obtain an octet. Covalent Bonding: Electrons are shared between two or more elements. Always between 2 non-metals. Nature of coordinative bond. Back-bonding. Bonding of metals to . p. -systems. Valence bond and hybridization. Each bond treated independently from the environment. Resonance concept. Impossibility to explain molecular geometries.
