A guide for A level students. KNOCKHARDY PUBLISHING. 2008 . SPECIFICATIONS. INTRODUCTION. This . Powerpoint. show is one of several produced to help students understand selected topics at AS and A2 level Chemistry. It is based on the requirements of the AQA and OCR specifications but is suitable for other examination boards.. 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. Metals. Look at the Periodic Table…. 75% of elements are metals!. Metals. They can vary a lot…. General Properties of Metals. Dense. Malleable. Ductile. Good conductors of heat and electricity. Shiny Lustre. CHEMICAL BOND – A force that holds two or more atoms together as a unit. Individual atoms will naturally bond together to achieve a lower energy state (to be more stable). 3B-1 (of 42). TYPES OF BONDS. Strong forces of attraction are responsible for the high melting point of most metals.. CA Standards. Students know . atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds. . Bonding Discussion. Bonding. . Ionic. . Covalent. . Metallic. Determined by difference in Electronegativity between atoms.. Ionic . Compounds. Crystalline . solids (made of ions) . High melting and boiling points . 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. SCH4U1. Mr. . Dvorsky. Ionic Solids. Result from the reaction of a metal and a non-metal. Because of the large . electronegativity. difference, electrons transfer from the metallic atom to the non-metallic atom and the ions that result attract each other. . C2 1.1 Chemical bonding. Key words:. A . compound. contains two or more elements which are chemically combined. Covalent. bonding – sharing electrons. Ionic. bonding – transferring electrons. Chemical bonding: . CA Standards. Students know . atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds. . Metallic Bonding. The chemical bonding that results from the attraction between metal . 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. . Day . 6. – Venn Diagram, . haber. Process. Metallic . Bonding, Properties of Substances reading, . Warm up. ON PAGE 23. What do ionic and covalent bonding have in common? What is different?. Time: . Metallic Bond – the force that holds metal atoms together. Metals do not form covalent bonds with one another because they do not have enough electrons in their outer shells to form stable octets..
