Increase your understanding of bonding and electronegativity. Increase your spatial skills and awareness using software designed by the CCDC. IB Topics 4 & 14. 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 5: Giant Covalent Structures, Metallic Bonding & Physical Properties. 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. 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!. Chemistry. Learning Goals . To be able to . explain and draw atomic structure. Elements. Elements are the . building blocks. of all . matter. on Earth. Elements are made up of . atoms. Differences in . . and Structure. IB Chemistry. Topic 4. . Bond - A force that holds . atoms . together and . makes . them . function as a . unit.. 4.1 Ionic Bonding. An . ion. is a charged particle. Ions form from atoms or from groups of atoms by . Higher Supported Study - Week 2 . Key Areas – Periodic Trends . The trends in . covalent radius . across periods and down groups.. The trends in . ionisation energies . across periods and down groups. . 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. IB Topics 4 & 14. 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 5: Giant Covalent Structures, Metallic Bonding & Physical Properties. 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. 4.4.1: Describe the metallic bond as the electrostatic attraction between a lattice of positive ions and delocalized ions. . 4.4.2. : Explain the electrical conductivity and malleability of metals. . multicomponent systems.
