2. # 4 Periodic Table Activity Procedures
Directions: Using your textbook pages 21D-22D complete the activity below.
Obtain a copy of the periodic table.
Label the groups (columns) 1-18 at the top of each column.
Label the periods (rows) 1-7 on the left side of your periodic table.
Using a dark color, draw a zig zag line separating the metals from non metals. This is called the stair case line.
Lightly color the metals yellow, non metals green, and metalloids purple. Make a key on the front of the pd table.
Define the following terms (6) on the front of your periodic table: nonmetals, metals, metalloids, groups, periods, and stair case line. Provide at least on example or fact for each.
