Trends Graphing Activity

Trends Graphing Activity

Create 2 graphs using the data provided on the element cards. The hand written number is the atomic number of each of the elements.

Graph 1- Trends in Chemical Properties

1.  Label the x-axis Atomic Number.

2.  Label the y-axis Number of Oxygen Atoms.

3.  Create a bar graph by plotting the oxide data from the element cards for each element in order of atomic number (1-20).

4.  Label each bar with the symbol for the element is represents.

Graph 2- Trends in a Physical Property

1.  Label the x-axis Atomic Number.

2.  Label the y-axis Boiling Point (K).

3.  Convert all boiling points to Kelvin. (K= ⁰C + 273)

4.  Create a bar graph using the boiling point data from the element cards for each element in order of atomic number (1-20).

5.  Label each bar with the symbol for the element it represents.

Questions

1.  Describe the patterns you observe on the Chemical Properties graph.

2.  Describe the patterns you observe on the Physical Properties graph.

3.  In which group(s) are the elements with the highest O in oxide numbers located?

4.  In which group(s) are the elements with the highest boiling points located?

5.  Predict which element should have the lowest boiling point: Se, Br, or Kr. Why?

6.  Predict which element should have the lowest O in oxide number: Te, I, or Xe. Why?
