1. SPI
The Periodic Table

2. Bell Work
- Bring something from your locker. This item does not need to be a textbook, but can be any one item that pops into your head. 

3. Objective:
Use the periodic table to determine the properties of an element. (SPI )

4. HYDROGEN
The properties of hydrogen are different from those of any other element.
It is placed in Group 1 metals because, like them, it has one valence electron.
It is sometimes separated to show that its properties are different.

5. Problem Solving: Hindenburg
It was the largest airship ever built; over eight-hundred feet long from its nose to its massive tail fins. It was the Hindenburg. In the space of 37 seconds the mighty zeppelin was destroyed in a fire that killed a third of its crew and passengers and left spectators crying in horror.

6. Problem Solving: Hindenburg
The Hindenburg was filled with hydrogen. Why was this a bad idea and what could they have done to perhaps have kept this tragedy from occurring?

7. What did we learn about Hydrogen ?

8. HYDROGEN It is a colorless, odorless gas. (physical)
Hydrogen gas must be used with caution because it is highly flammable; it forms easily ignited explosive mixtures with oxygen or with air (because of the oxygen in the air).
(chemical property)

9. IF (Bell Work)
Grab a ½ sheet off of the table in the front of the room (do not write on these.)
Then start a new section in your science notebook called, “Periodic Table”
We have 40 minutes, I need you ready to go or you will get left behind.

10. Objective:
Use the periodic table to determine the properties of an element. (SPI )

11. The Periodic Table
Dimitri Mendeleev arranged the elements in order of their atomic mass.
What makes up the atomic mass of an atom?
However, some elements did not seem to fit properly.
Today, elements are arranged in order of the atomic number.
What does the atomic number of an element tell you about that atom?

12. Periods  
Each horizontal row is called a period (# OF ENERGY LEVELS).
Periods are numbered 1-7.

13. How many energy levels does Argon (Ar) have? Valence electrons?

14. Groups (1-18)
GROUPS- are vertical columns (# OF VALENCE ELECTRONS  w/ exception of Groups 3-12)
ELEMENTS IN THE SAME GROUP SHARE SIMILAR CHEMICAL PROPERTIES (REACTIVITY).

15. Give an example of 2 elements that share similar chemical properties.

16. REACTIVITY
The number of electrons in the outer energy level determines an element’s reactivity.

17. Octet Rule
Every element’s goal is to fill its outer energy level or get 8 electrons in the outer energy level.
Then it will react (chemically bond) with another element and become stable.

18. Reactivity Increases
REACTVITY
REACTIVITY INCREASES
