Directions for Periodic Table Activity Line Graph 1. For each of the atom samples examined in the chart on the previous page, plot a point at the spot where the number of electrons and the number of protons intersect. 2. Label the point with the atomic symbol of the atom it represents. 4. Then add the following atom elements on that same line in a different color. (Label each new atom the way you did with the previous atom examples just use a different color.) a. Barium b. Platinum c. Radium d. Krypton e. Dysprosium 5. Place a key on the graph showing the colors of the tested atoms and the added atoms. DO NOT WRITE ON THIS SHEET! ATOM LAB Line Graph 3. After plotting all points, connect them to form a line graph.
