Chapter 7 p

2. NGSS: 8.2 The Periodic Table
SWBAT: use the periodic table to identify in simple compound
If you understand the arrangement of the elements on the periodic table, you can use the table as a tool for predicting the structure of an atom
Elements are found everywhere around us: the air, earth, our bodies
The most common element is nitrogen, oxygen, and hydrogen.
The period table is the arrangement of the elements according to the atomic properties

3. “Candy Table”
Objective:To create a table arrangement based on properties of an item
State the Question: How can you arrange a vary of candies
Hypothesis:
Data: Chart
Analysis: Describe the different ways you arranged your candies? Be exact, use terms like rows, columns, groups, space
Conclusion:

4. Candy Table Conclusion:
Describe the process of arranging candies within your group.
What changes did you make with your arrangement? Did it make it better? Why or why not?
Describe what happen when you added two new pieces of candy.
Reflection: What did you like, dislike? What would make this activity better for understanding the creation of the Periodic Table

5. Dmitri Medeleev ( )
Chemist from Russia in the late 19th century
Wrote the book “Principles of Chemistry
65 know elements (now 94 naturally 118 on table)
Looked for pattern and found occurring 7 element groups
Called his arrangement the periodic table
Organized it based on predictable properties and atomic weight
Left spaces for undiscovered elements
Germanium

6. Homework : Element Research Activity
Choose two elements to make index cards
On the Blank side:
Write the element name, symbol, atomic number and mass
Glue or draw a picture of your element (raw form or use for element)
Make sure element is neat, clear, accurate, and colorful

8. Homework : Element Research Activity
On the line side:
Research the use for the element
The history of the element
How the element was given its name
Idenify the uses of the element (at least three)

10. Extra Credit: Biography Research Paper

12. The Periodic Table Created in 1868 by Dmitri Medeleev
There are 94 natural elements and 118 total elements listed on table
In horizontal rows, periods, according to atomic number
Each row begins with a new energy level (# of valence electrons in outer shell)
There are 7 rows
In vertical Columns, groups or families, according to chemical/physical properties
There are 18 groups

15. Jokes
I I was going to tell you a chemistry joke, but the only ones I have are Boron, and all the good ones Argon.wanted to make a clever chemistry joke, but all the good ones ARGON.

16. Groups and Periods 7 Periods 18 Groups/Families
horizontal row of elements from left to right
The physical and chemical properties follow repeating pattern based on increasing and repeating pattern of protons, neutron, and electrons
18 Groups/Families
Vertical columns from top to bottom
Similar chemical and physical properties
Similar electron valence

17. Classes of Elements Metals: Metalloids Nonmetals
Most elements are metal
Valence less than half filled
Solid at room temperature
Metalloids
Semimetals
Border the “zigzag line” on periodic table
Share properties with metal and nonmetal
Valence is half a complete set of electrons
Nonmetals
To the right of the “zigzag line”
More than half are gases
Valence more than half filled
Metals (Read Figure 3 adn 4 p and write describes of each class of element)
Shiny
Most are ductile
are malleable
Metalloids
Hard and brittle
Nonmetals

18. Battleship Periodic Table
Materials:
color of periodic table, clear cover sheet, two dry eraser mark for each player
Directions:
Fill-in one metal, nonmetal, and metalloid with one color; Call out a period number (1-7) and a group number (1-18); mark X for hits in one color and O for misses.
Winner: Whoever hits all 3 first wins!!
Exit Ticket: Where do you find elements that conduct electric current and can be pounded into thin sheets?

19. Alkali and Alkaline Metals
Group 1: Alkali Metals
Group contains: metals
Electrons in outer level: 1
Reactivity: Very reactive
Properties: softness, color of silver, shininess; low density
Draw Sodium and Potassium (use Lewis Dot Model) What is similar?

20. Group 2: Alkaline-Earth Metals
Group contains: metals
Electrons in outer level: 2
Reactivity: Very reactive but less than alkaline
Properties: color of silver, higher density
Draw a Lewis Dot Diagram of Beryllium and Magnesium
Exit Ticket: Color Group 1 Red and Group 2 Pink

22. Do Now
Write the elements that make up the following compounds:

23. Group 3-12: Transition Metals
Electrons in outer level: 3
Reactivity: Less reactive,
Properties: shininess, good conductivity of thermal energy and electric current, density and higher melting point
Bigger group (40 members)
Widely used, ability to form strong metal alloys, malleability, conductivity, and beauty
Make a list of transition metal and identify the metal and its use
