Homework for 10/2

If you did not answer the 12 questions that were given in class on Monday, here they are and finish and turn in on Thursday.

Remember you also have to be prepared to present with your group on Thursday as well.

Periodic Table Activity

1. Explain why light is said to have a dual nature.

2. Draw a wave and label the crest, trough, and wavelength.

3. Draw a picture of the different types of electromagnetic radiation and show the high energy             low energy and long wavelength            short wavelength. Make sure to label all the different types of energy.

4. Explain what happens when an electron in an atom becomes excited.

5. When an electron is excited a photon is ____________. When an electron returns to ground state a photon is _____________.

6. Draw the shape of a “s” orbital.

7. Draw the shape of a “p” orbital.

8. Draw the shape of a “d” orbital.

9. Draw and label a periodic table with the atomic charges

for the groups shown. Give for groups #1, 2, 13-18.

10. Show how atomic size changes across and down the atomic period. Draw in how the size of the atom changes and draw arrows showing how it changes.

11. Metals tend __________ electrons. Nonmetals tend to __________ electrons.

12. Show how the ionization energy changes as you move across the period and down the groups of the periodic table.  Draw the table and label with arrows and words to show the changes of ionization energy of the periodic table.

Group assignments for 10/2

Each table group will present about their questions from Chapter 11.  Each group member is expected to help with the presentation and contribute.  You will be graded on your participation and effort.

Here are the assignments for each group. There is a separate posting under homework for 9/30 & 10/2 that gives all the questions for the assignments.

Table Group #1: Question #1 & #2
Table Group #2:  Question #3 & #4
Table Group #3: Question #5, #6, #7 & #8
Table Group #4: Question #9 & #10
Table Group #5: Question #11 & #12

Alien Periodic Table Questions

Answer all questions and be VERY specific about your characteristics for the alien.  Don't tell me the same fingers, tell me exactly how many fingers that they have in common for example.

Alien Periodic Table

Procedure:

**Create a periodic table of elements that has 8 groups and 5 periods.  The group aliens must be exactly the same in ONE way (the Key Similarity) and must also share one feature that changes in a periodic pattern as you move down the group (the Varying Trait).  Within each period, the aliens must be exactly  the same in ONE way (the Key Similarity) and must also share one feature that changes in a periodic pattern as you move across the period (the Varying Trait).

**Two aliens are missing from your set, leave empty spaces to draw them in later.

Questions:

1. How many groups of aliens do you have? ________

    How many periods of aliens do you have? ________

2. Draw in the missing aliens and describe.

    Description of missing alien #1                                     Drawing of missing alien #1

    (Give 5 characteristics of the alien)

    1.__________________________

    2. __________________________

    3. __________________________

    4. __________________________

3.  Give detailed information about your chart of aliens. Then list the Key Similarity and Varying Trait for the aliens in that group.  Be very specific about what is staying the same and changing.

                                    Key Similarity (stays same)                      Varying Trait (changes)

Analyzing and Comparing Questions:

5. Draw a model of a hydrogen-1 including protons and electrons.

6. What do the groups of aliens have in common (how are they similar) to the groups/families of atoms on periodic table? Think about how the groups on the periodic table are similar and compare to your aliens.

7. How are the periods of the aliens have in common to the periods on the periodic table?

8. Compare the alien in group 1, period 1 to the atom in group 1, period 1 (hydrogen) on the periodic table. How are they similar; compare their characteristics. Think about what are the characteristics of the hydrogen atom
