Mr. Zehner's Chemistry Class

Tuesday, November 30, 2010

In class:

Completed "Trend Setter" POGIL Activity - Students should now be able to

Identify elements with similar chemical and properties using the periodic table
Identify metals, non-metals, and metalloids using the periodic table.
Predict general trends in atomic radius, first ionization energy, and electronegativity of the elements using the periodic table

Assessment tomorrow (H & G) or Wednesday (B&F)

Please Review the notes, problems, and vocabulary associated with topics below.

Quantum numbers
Electron configurations
Periodic Table trends

In class:

Reviewed Periodic Table Worksheet Answers
Reviewed homework questions from textbook

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

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.

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!
