# 4 Periodic Table Activity Procedures Directions: Using your textbook pages 21 D-22 D complete the activity below. 1. Obtain a copy of the periodic table. 2. Label the groups (columns) 1 -18 at the top of each column. 3. Label the periods (rows) 1 -7 on the left side of your periodic table. 4. Using a dark color, draw a zig zag line separating the metals from non metals. This is called the stair case line. 5. Lightly color the metals yellow, non metals green, and metalloids purple. Make a key on the front of the pd table. 6. Define the following terms (6) on the front of your periodic table: nonmetals, metalloids, groups, periods, and stair case line. Provide at least on example or fact for each.
