Procedure
Part 1: Customizing a Periodic Table
Use a textbook or other valid source to determine which elements are metals, nonmetals, metalloids (called semimetals in some texts), alkali metals, alkaline earth metals, transition metals, halogens, and noble gases.
Download and print a copy of the Periodic Table of Elements.
Use colored pencils, colorful highlighters, or computer drawing tools to devise a schematic for designating each of the following on the periodic table:
Group numbers
Period number
Labels for these groups: alkali metals, alkaline earth metals, transition metals, inner transition metals (lanthanides and actinides), other metals, metalloids (semimetals), other nonmetals, halogens, and noble gases
Metals, nonmetals, and metalloids
Note: Write the group and period numbers and color/highlight each element for categorization. Be sure to include a key for the schematic.
Take a photo of the completed periodic table and upload the…
