Week of  10/23-10/27    2023

Chapter 5   Periodic Table

 

Monday 10/23   

Chapter 5 section 1

Objective: TSW be able to explain the role of Mendeleev and Mosesly in the development of the periodic table. TSW be able to explain how the periodic law can be used to predict the physical and chemical properties of elements.

Materials: textbook, paper, pen

Activities: Lecture and visual aids will be used to discuss the objectives above.

Handout: none

Homework: read pp.123-137.

 

Tuesday 10/24 

Chapter 5 Section 2

Objective: TSW be able to describe the relationship between electrons in sub-levels, and the length of each period of the periodic table. The student will be given the location of the periodic table and they will be able to give the general properties of each section.

Materials: textbook, paper, pencil

Activities: TSW take a review quiz over section 1 and 2. In a “Round Robin organized chaos” the class as a whole will work and discuss how each part of the periodic table has certain properties because of its electron configuration.

Handout: Review Quiz Chapter 5 sections 1 and 2.

Homework: nothing new.

Wednesday 10/25

Chapter 5 Section 3

Objective: TSW will be able to determine how the Atomic, ionic, redii, ionization energy, electron affinity, and electronegativity increase or decrease across the periodic table.

Materials: textbook, paper, and pen.

Activities: The class will have a lecture and use a power point to illustrate the above objectives.

Handout: none

Homework: nothing new

 

Thursday 10/26 

Chapter 5

Objective: The student will be able to identify a set of flame-test color standards for selected metal ions. They will relate the colors of a flame test to the behavior of excited electrons in a metal ion. The student will also identify an unknown metal ion by using a flame test.

Materials:  Standard lab Equipment and certain metals. 

Activities: Lab over flame test

Hand out: lab procedure

Homework: none

 

Friday 10/27  

Chapter 5 section 3

Objective: The student will be able to define valence electrons, and state how many are present in atoms of each main-group element.

Materials: Textbook, pen, paper

Activities: Group discussion and a power point will be used to explain why valence shell electrons are used in bonding elements.

Handout: none 

Homework:  read
