1. Periodic Table of Awesomeness (Elements)

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

3. 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

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

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

6. 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

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

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

9. Metals/ Metalloids/ Nonmetals
Metals: (left of the staircase) – Shiny, good conductors, malleable
Nonmetals – (right of staircase) – brittle, Dull, poor cunductors
Metaloids (both) semiconductors

10. Groups with Specific Names
Group 1: Alkali Metals Group 2: Alkaline Earth Metals Group 17: Halogens Group 18: Noble Gases
Halogens – Most reactive

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

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. The most common molecules that make up living organisms
C H O N P S
The most common molecules that make up living organisms
Carbon
Hydrogen
Oxygen
Nitrogen
Phosphorus
Sulfur
CHONPS- Found in organic compounds

18. Molecules that naturally appear in pairs such a O2
Diatomic Molecules
Molecules that naturally appear in pairs such a O2
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
- 1 +3
+/- 4
- 3
- 2 +2
