Cht 6 - Periodic Table

This unit explores the development of he Periodic Table, its general layout, the key element types and families, periodic trends and the usefulness of the periodic table for use by chemists. The following learning objectives will be covered:

1. Discuss the major contributions to the development of the periodic table.
2. State the periodic law and describe the importance of the periodic table as a tool.
3. Explain why elements in a group have similar properties in terms of electron configurations.
4. Write the Lewis Dot structures for most elements.
5. Identify the four blocks of the periodic table and discuss the uniqueness of each.
6. Define metals, nonmetals and semimetals and discuss the properties of each (macro and micro).
7. Identify the various families and discuss their properties.
8. Define the term periodic trend and identify four such trends and discuss how electrons configurations relate to each.
9. Use the periodic table to predict various relative properties of any specified element.
10. Identify key elements from each group by its properties and uses.
