Transcript

1.)Refer to the graph that you created in Part I of this assignment. Describe the general trend or patterns that you observed in the atomic radius as you go across the periodic table.

  • It had a negative trend. With the correlation being that as the radius decreased number uncreased.

2.)In Part II of this assignment, you graphed the atomic radius of some elements from group 14 on the periodic table. What is the general trend for atomic radius going down that group?

  • I noticed that in this graph there was a positive trend. As the periodic number increased, the atomic radius did too.

3.)What element in Period 5 of the periodic table is a member of Group 14?

  • Tin (Sn)

4.)The word interpolate means to use a given line graph to find unknown points between the plotted points of the graph. Use your line graph from Part II to interpolate, or estimate, atomic radius of Tin (Sn).

  • i would say between 120 and 170.

5.)Tin's actual atomic radius is 140 pm. Use the math equation below to determine the percent error of your estimated value 140-50/140x100 7% off the placement of the graph interferes with the i viewed it.
