Objectives
Graph values for atomic radii.
Interpret trends in the periodic table of elements.
Materials
For this Quick Lab you will need the following supplies:

graph paper.
a periodic table .
Information
In this lab, you will create a graph of atomic radius values and use the graph to interpret trends in the periodic table. You will recognize that elements are grouped in the periodic table according to similarities of their properties.

Procedure
On your graph paper, create a line graph using the values in the Predicting Properties – Range of Values data table attached above. Label the x-axis (horizontal) “Atomic Number” and the y-axis (vertical) “Atomic Radius.” Review the range of values in the table to determine an appropriate scale for your graph.

Questions
Describe the pattern you see in the graph.
Compare your graph to the periodic table of elements. How does the pattern relate to the structure in the periodic table?
What trends do you observe about the the relationship between atomic radius and atomic number in the periodic table?
Based on these trends, what are the approximate values of the atomic radii of elements 10, 18, and 20?

Answer 1

general information to help you answer the questions:

The pattern in the graph will depend on the specific data provided in the Predicting Properties – Range of Values data table. Generally, atomic radius increases as you move down a group in the periodic table and decreases as you move across a period from left to right.

The pattern in the graph should correspond to the grouping of elements in the periodic table. Elements in the same group typically have similar properties, including atomic radius.

As mentioned in #1, atomic radius generally increases as you move down a group and decreases as you move across a period from left to right.

Without access to the specific data in the Predicting Properties – Range of Values data table, it's not possible to give the exact values of the atomic radii of elements 10, 18, and 20. However, based on the trends described in #3, element 10 (Neon) would have a smaller atomic radius than element 18 (Argon) and element 20 (Calcium) would have a smaller atomic radius than both Neon and Argon.
