Homework:

Create a Periodic Table - Create a table to be used in an introductory chemistry course that summarize the main points bulleted below.  Choose how to represent the items/ideas.  Include a key to explain any coding used.

• Identify the elements as metals, nonmetals, or metalloids
• Identify the elements as solids, liquids, or gases at room temperature
• Include the following family names: Alkali Metals, Alkaline Earth Metals, Chalcogens, Halogents and Noble Gases
• Identify the Lanthanide & Actinide Series
• Identify the s block, p block, d block, and f block
• Include arrows showing an increasing trend in periods and groups for the following trends
• electronegativity
• ionization energy
• atomic radii

Wednesday, November 24, 2010

In class:

• Continued POGIL "Trend Setter" Activity where students discovered the trends of the periodic table of elements
• As a supplement to the POGIL Activity, students should look at the presentation and video below.

Homework: (Due Monday after break)

• Questions #21, 22, 25, 29 - 35 (p. 189)

Monday, November 22, 2010

In class:

Because of my absence on Friday, many classes received different assignments. In general, all classes reviewed electron configuration as well as introductory information regarding the formation of the periodic table.

Regardless of class, all students are responsible for having read all of Chapter 5 and completing the notes and questions associated with each section.

Homework:

The "Make Your Own Periodic Table" that students completed on Friday were returned. Each student is responsible for answering the questions below based on their periodic table.
1) What trends exist looking across the rows from left to right?
2) What trends exist looking at the columns from top to bottom?
3) What changes would you make to your table to increase the trends seen? What problems do you see where elements do not fit the trends? Analyze and Explain.
**The evaluation of this activity is more important than the creation of the table.**

WARNING: I STRONGLY encourage all students to review quantum numbers and electron configurations to prepare for a possible quiz later this week!

Homework:

• No worksheet tonight, instead. . . .
• Read Section 4.2 taking notes and answering section questions
• Flame Test Lab Report Due Friday (format below)

Name

Block

Date

Lab Partners:  Partner 1, Partner 2

A very good title (What was manipulated?  What was observed?  What was studied?)

Purpose:

            In a single paragraph write the purpose for this experiment. (Minimum of 5 sentences)

Data:

Put a title for your data table here.

HEADING	HEADING	HEADING

Questions:

1.      Based on your observations from this lab, what is/are the unknown compound(s)?  To receive full credit, you must justify your answer with a detailed explanation consisting of no less than 3 full sentences for each unknown.  (Write your response below the data table you created)

Answer in bold font.

2.      Is a flame test a qualitative or quantitative test for the identity of an unknown compound?  Explain.

Answer in bold font.

3.      If you look at the stars at night you will find that some stars are different colors than others.  Stars release different amounts of energy during their lives.  How might astronomers use line spectra to distinguish the ages of certain stars?

Answer in bold font.

4.      Salts consist of a positive metal ion and an anion (an ion with a negative charge).  An example would be NaCl – sodium metal (Na⁺) with a chloride anion (Cl^-).  When doing this lab, do you think it is important to use salts with the same anions.  Why or why not?

Answer in bold font.

5.      When a glass rod is heated, a yellow-orange flame is observed around the point of heating.  What does this yellow-orange flame indicate?  Why is it observed when glass is heated?

Answer in bold font.

6.      Use the Rydberg equation to calculate how much energy is necessary for an electron to occupy the n=1 shell of a hydrogen atom.  (Give your answer in proper scientific notation with 3 significant figures.)

Do NOT type this answer.  Write the answer in by hand.

7.      Use the Rydberg equation to calculate how much energy is necessary for an electron to be excited from the n = 1 shell to the n = 2 shell of an atom.  (Hint:  ΔE = E_final - E_initial, Use your answer from above as the initial value for energy and use n=2 to calculate the final value for energy.)

Do NOT type this answer.  Write the answer in by hand.
