1. Announcements IAN Notebooks will be GRADED ON FRIDAY!!! Make sure you have everything glued in and completed before then. If you have not completed CBA Corrections, you will be given a ZAP Lunch Detention. If you do not attend ZAP and complete CBA Corrections, you will be written up. NO EXCEPTIONS!

2. Periodic Table of Awesomeness (Elements)

3. Information on Each Element There are 4 main pieces on each square of the periodic table:

4. Information on Each Element There are 4 main pieces on each square of the periodic table: Atomic Number: The number of protons the Element has

5. Information on Each Element There are 4 main pieces on each square of the periodic table: Element Symbol: Letter(s) that represent the element.

6. Information on Each Element There are 4 main pieces on each square of the periodic table: Element Name

7. Information on Each Element There are 4 main pieces on each square of the periodic table: Atomic Mass: The mass of the atom. Atomic Mass = Protons + Neutrons

8. Groups/Periods Groups- Vertical columns on Periodic Table

9. Groups/Periods Period- Horizontal Rows on Periodic Table

10. Metals/ Metalloids/ Nonmetals Metals Metalloids Nonmetals

11. Trends in Periodic Table Atomic Radius – How big the atom is Biggest Smallest

12. Trends in Periodic Table Atomic Radius – How big the atom is

13. Trends in Periodic Table Electronegativity/ Electron Affinity– How strongly the nucleus attracts the electrons Strongest Weakest

14. Trends in Periodic Table Electronegativity/ Electron Affinity– How strongly the nucleus attracts the electrons

15. Valence Electrons The number of electrons in the atom’s outer shell. This affects how reactive an atom is. This is indicated for each column/group by the number in front of the letter above

16. Valence Electrons Column/Group 1A has 1 valence electron Column/Group 8A has 8 valence electron (except for He which has 2)

17. C H O N P S The most common molecules that make up living organisms Carbon Hydrogen Oxygen Nitrogen Phosphorus Sulfur

18. Diatomic Molecules Molecules that naturally appear in pairs such a O 2 These are still elements, NOT compounds

19. Oxidation Numbers These numbers are used to determine chemical formula of compounds. Number is between 1 – 4 Positive number means Group members can GIVE an electron. Negative number means Group members can TAKE/STEAL an electron

20. Oxidation Numbers +1 +2 +3 +/- 4- 3 - 2 - 1 0
