Lesson 4 - Trends of the Periodic Table

• Science
• 9th Grade

TRENDS

             Learning Intentions: 

What? Identify the trends of the PT

Why? To make it easier to determine the properties of each element and the similar chemical composition of elements

Success Criteria:  I can: 

Identify: -groups - periods - 

Identify the Relationship between:

     -groups & VE

     -periods & Energy levels

Identify the state of matter at room temperature 

Identify the pattern in Density

What patterns can you find in this Periodic Table?

Horizontal Rows are called PERIODS. 

  What do the elements in each Period  have in common?

PERIOD 1

PERIOD 2

PERIOD 3

Vertical Columns are called GROUPS or FAMILIES. 

  What do the elements in each Group have in common?

Group 2

Group 1

Group 13

Group 14

Group 15

Group 16

Group 17

Group 18

Research It - Organize It:

• Glue the PT in your Spiral. 
• Use the following resources to research the trends of the PT. 
•     1. Interactive PT HERE 
•     2. Video - NEXT SLIDE

On your PT, you are to annotate/label the trends that are listed HERE.  What you do in your Spiral will serve as your notes.

The location of an element on the periodic table can tell us the

1. properties and reactivity of the element
2. the properties and size of the element
3. the atomic number and properties of the element
4. the reactivity and atomic mass

00:51

Horizontal lines on the periodic table are called ___ and have the same number of ____.

1. groups, energy levels
2. groups, valence electrons
3. periods, energy levels
4. periods, valence electrons

01:03

Energy levels are located in the ___ and hold ____.

1. electron cloud, neutrons
2. nucleus, electrons
3. electrons cloud, protons
4. electron cloud, electrons

01:15

The vertical columns on the periodic table are called ____.

1. valence electrons
2. groups
3. energy levels
4. periods

01:42

Silver, Gold, and Copper are found in the same group. They are all used to make jewelry because they all have the same ____.

1. energy levels
2. number of valence electrons
3. number of electrons
4. properties

Practice It: 

1. Click HERE to view different Bohr Models. 
2. Use what you have learned about the PT to help you answer each question. You may use your Spiral to help you. 
3. Write your answers on the Answer Sheet I gave you in class. If you are absent, use your own paper. 
4. Turn in your Answer Sheets to your Block Basket.
