Trends of the Periodic Table

Part 1: Little People Sort

In this activity you will be arranging the little people in a specific pattern that your group chooses.  Find as many trends/patterns as possible.  The more the better. 

Procedures:

Data Analysis:

1. What are some of the physical properties that helped you organize the little people?

the arms and :(    [faces]

2. What do the little people have in common in each period?

3. What do the little people have in common in each group?

Part 2: Grouping the Elements

Use Pages 334 - 335, 338 - 341 in your textbook to do this section of your wiki.

For each group of elements, you will need to: (there are 9 groups)

• Insert an image of the periodic table and circle the group of elements
• Name of the group (skip the transition metal group)
• Number of electrons in the outer level (also called valence electrons)?
• Do they give or take electrons?  How many do they give or take? (read page 354 - 355 to help you find out this answer)
• Number of electron rings?  (If you look at enough examples on pages 353 - 358 you can figure out this answer)
• Shared Properties

Example 1: 1 electrons in the outer level (valence electrons) Give or Take valence electrons.  Gives or takes 1 valence electrons 2 electron rings Shared Properties: Soft; silver-colored; shiny; low density

Example 1: 2 electrons in the outer level (valence electrons) Give or Take valence electrons.  Gives or takes 2 valence electrons 3 electron rings Shared Properties: silver-colored; more dense than alkali metals

Example 1: 3 electrons in the outer level (valence electrons) Give or Take valence electrons.  Gives or takes 3 valence electrons 4 electron rings Shared Properties: Solid at room temperature

Example 1: 4 electrons in the outer level (valence electrons) Give or Take valence electrons.  Gives or takes 4 valence electrons  5 electron rings Shared Properties: solid at room temperature

Example 1: 5 electrons in the outer level (valence electrons) Give or Take valence electrons.  Gives or takes 5 valence electrons 6  electron rings Shared Properties: all but nitrogen are solid at room temperature

Example 1:  6 electrons in the outer level (valence electrons) Give or Take valence electrons.  Gives or takes 6 valence electrons 7 electron rings Shared Properties: All but oxygen are solid at room temperature.

Example 1:   7 electrons in the outer level (valence electrons) Give or Take valence electrons.  Gives or takes 7 valence electrons   8 electron rings Shared Properties: Poor conductors of electric current; react violently with alkali metals to form salts; never found uncombined.

Example 1:   8 electrons in the outer level (valence electrons) Give or Take valence electrons.  Gives or takes 8 valence electrons 7 electron rings Shared Properties: colorless, odorless gases at room temperature.

Example 1:   1 electrons in the outer level (valence electrons) Give or Take valence electrons.  Gives or takes 1 valence electrons   2electron rings Shared Properties:   colorless, odorless gases at room temperature; low density ; reacts explosively with oxygen.

Data Analysis:
1. List all the trends/patterns that you have noticed in each Period?  The more you notice, the better.

• the atomic number increases
• the number of protons and electrons increases
• the valence electrons increase
• number of electron rings saty the same
•  the atomic weight increases

2. List all the trends/patterns that you have noticed in each Group?  The more you notice, the better.

• the number of electrons rings incraeses
• the atomic number increases
• the number of protons and electrons increase
• give or take the same amount of electrons.
