Megat Yusoff Jan2010 PSMMY UTP 1 LECTURE OUTLINE m Introduction m Atomic Structure m Electronic Structure of an atom Jan2010 PSMMY UTP 2 m Atomic Bonding m Conclusion Learning Outcomes Today… what do I want you to learn? To describe the structure of an atom. Define electronegativity of atoms in relations to the periodic table. Jan2010 PSMMY UTP 3 Able to interpret the periodic table. To explain the differences between ionic, covalent, metallic, hydrogen and van der Waals bonds and determine which type will be present given any two atoms based on their electronegativities. To note which materials exhibit each of these bonding types. To distinguish between primary and secondary bondings. Introduction Structure of materials can be examined at 4 levels Jan2010 PSMMY UTP 4 •Atomic structure •Atomic arrangement •macrostructure •microstructure Introduction Atomic structure Bonding Jan2010 PSMMY UTP 5 Types of materials Properties ATOMIC STRUCTURE
