Why does Flourine has a larger atomic radius than Oxygen when it comes after Oxygen in the period? 

- -- Periodic Trends: Graphing Atomic Radii The periodic table is a wonderful source of information about all the elements scientists have discovered. In this activity, you will investigate the relationship among elements atomic numbers, radii, and positions in the periodic table. The radii for elements with atomic numbers 3-38 are given in table 1, The radii are so small that a very small metric unit called a picometer is used. A picometer (pm) is one trillionth of a meter (1 x 102 m). In this activity. you will graph the atomic radii of the elements with atomic numbers 3-38 and examine the graph for repeating patterns. Table 1: Atomic Radii Name and symbol Atomic Atomnic radius Name and symbol Atomic Atomic radius number (picometer) Aluminum Argon Arsenic number (picometers) 143 191 Al 13 Magneslum Mg 12 160 127 Ar 18 33 Manganese Mn 25 10 As 121 Neon Ne 131 Beryllium Boron Bromine Calclum Carbon Chlorine Chromium Be 4 112 Nickel Ni 28 124 B 5 85 117 Nitrogen Oxygen Phosphorus Potassium Rubldium Scandlum Selenium Silicon Sodlum Strontium Sulfur Br 35 8 60 Ca 20 197 77 91 15 9. 17 K 19 231 248 Rb 37 24 128 21 Sc Se Si 162 119 118 Cobalt Copper Fluorine Gallium Co 27 29 125 34 Cu 128 14 6. 31 F 69 Na 11 186 Ga 38 16 215 103 147 134 Sr Germanlum Ge 32 123 Iron Fe 26 126 Titanlum TI 22 Vanadlum Zinc 134 201 156 V Zn 23 Kr LI 36 Krypton Lithium 3 30 134 Procedure 1. On the graph paper, label the horizontal axis with the numbers 0-38 to represent the atomic numbers of the elements you will be plotting. 2. Label the vertical axis by ten with numbers 0- 280. These numbers represent the atomic radii. 3. Plot the atomic radius for each of the elements with atomic numbers 3-38. Label each point with the corresponding element symbol. When you have finished plotting points, connect the plotted data to create a line graph.
