Periodicity


 * Periodicity was a difficult unit because of the high level thinking skills needed to analyze patterns. You should watch and do the activities with the GPB episodes first, then read the tutorials and do the practices. I have included the standards, essential questions, and the lists of knowledge and skills you must acquire in order to master this unit. ** toc

Each section of the unit is in RED
=Georgia Performance Standards:  = a. Discriminate between the relative size, charge, and position of protons, neutrons, and electrons in the atom. a. Use the Periodic Table to predict periodic trends including atomic radii, ionic radii, ionization energy, and electronegativity of various elements. b. Compare and contrast trends in the chemical and physical properties of elements and their placement on the Periodic Table.
 * Sc3. Students will use the modern atomic theory to explain the characteristics of**
 * atoms.**
 * SC4.** **Students will use the organization of the Periodic Table to predict properties of elements.**


 * =Essential Questions: =

**Unit Essential Question:**
How can the periodic table be used to predict properties of elements? || How is the periodic table organized ? || v Atomic radii v Ionic radii v Ionization energy v Electronegativity ||
 * == Lesson Essential Question: ==
 * How can you predict trends in:
 * How can you determine the physical and chemical properties of elements by their location on the periodic table? ||

=What students should know and be able to do: =
 * 1) How the periodic table is organized
 * metals,nonmetals,semimetals
 * groups and periods
 * names of groups/periods
 * valence/charge of groups

2. Predict trends by using graphs for: (Use a calculator to graph)
 * atomic # and atomic mass
 * other general trends(density, etc)
 * atomic radii
 * ionic radii
 * ionization energy
 * electronegativity

3. Predict properties of elements by their location on the periodic table
