Procedure

Part 1: Customizing a Periodic Table

1. 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.
2. Download and print a copy of the Periodic Table of Elements.
3. 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.

1. Take a photo of the completed periodic table and upload the image into Photo 1.

Part 2: Properties of Element Groups

1. Use a textbook or other valid source to research the physical and chemical properties of each element listed in Data Table 1 using the following as a guideline:
   • Ductile (able to be deformed without losing toughness) and malleable (able to be hammered or pressed permanently out of shape without breaking or cracking) or not ductile or malleable
   • Good, semi, or poor conductors of electricity and heat
   • High or low melting and boiling points
   • Occur or do not occur uncombined/freely in nature
   • High, intermediate, or low reactivity
   • Loses or gains electrons during reactions or is not reactive

Part 3: Group Name and Number

1. Use the periodic table to identify the group name and group number of the elements listed in Data Table 2.
2. Record whether the elements are metals, nonmetals, or metalloids in Data Table 2.
3. Use a textbook or other reliable source to match each of the following descriptions to the correct element listed in Data Table 2:
   1. Pale yellow, odorless, brittle solid at room temperature, nonconductor
   2. Silvery white, relatively soft, low density, conductive solid that is not found as a free element in nature but commonly found combined in alloys with copper or nickel
   3. Metallic luster and grayish solid, very common in rocks and gemstones such as amethyst and opal, semiconductor
   4. Not found as a free element (uncombined) in nature, reddish-brown liquid that vaporizes readily at room temperature to a red gas with a strong disagreeable odor
   5. Silvery-white, ductile, malleable, conductive solid with a high melting point for this type of element
   6. Colorless, tasteless, and odorless gas, unreactive, nonconductive
   7. Soft, easily cut with a knife to expose a silvery surface that rapidly oxidizes in air; never found uncombined in nature
