Atomic Radius: Trends in the Periodic Table
Use two different colored pencils to indicate metals, nonmetals, and metalloids on the blank periodic table below. Allow the two
colors to blend for the metalloids. Provide a key for identification. Label each of the family names for the groups, include the
lanthanide and actinide series. Then draw arrows that indicate increasing atomic radius.
