Unit 3: The Periodic Table

Unit Objectives:

At the completion of this unit, students will be able to

1. Describe the organization of the original periodic table and how it has evolved into the modern one.

2. Locate the various groups and periods in the periodic table, state the special names, and describe the general properties associated with each.

3. Identify where metals, non-metals, and metalloids are located on the periodic table and explain how their physical & chemical properties differ from each other.

4. Identify the state of matter each element exists in at room temperature.

5. Predict, based on its position in the periodic table, the properties (appearance, electronegativity, and ionic charge) of a given main group element. Give examples of other elements that would have similar properties, and explain why they would have similar properties.

6. Explain, based on repeating patters of core & valence electrons, the organization of the periodic table.

7. Compare the relative sizes of parent atoms and their resulting ions and explain why this is so.

8. Identify, apply, and explain the periodic trends of atomic radius, ionization energy, and electronegativity.
