Part IV: “Customizing Your Own Periodic Table”

In this section you will customize the plain table given to you. Use crayons or pens to do this. You will be scored on meeting the items below and the visual appearance and neatness of your table.

Visit this site: http://go.hrw.com/resources/go_sc/periodic/SSHK1PER.PDF

In an empty area above the table make a diagram (box) that shows:

• Where the element symbol is
• Where atomic number is located
• Where atomic mass is located
• Add any new elements that are not present on your table
• Number the groups (vertical columns) 1-18
• Number the periods (rows) 1-7, 6 and 7 (6 and 7 are below the main section)
• Color elements belonging to each of the following groups: Non-metlas, Alkali Metals, Alkaline-Earth Metals, Metalloids, Transition Metals, Halogens, Noble Gases, Rare-Earth Metals (8 groups total)
• Choose a different color for each group. Make a legend below the table showing the colors for each group/family.

Part V: “Periodic Trends”

The periodic table is called such because many properties are periodic functions of their elements. In this section you will define each of the periodic properties and describe how the properties vary across a row and down a column of the periodic table.

• Cation
• Anion
• Ionization energy
• Electron affinity
• Electronegativity
• Metallic character

Part VI: “Representations of the Periodic Table”

As you search the sites below, be aware of the different portrayals of the periodic table. What are the different tables illustrating? Which do you like best?
