1. Properties & Elements

2. Question of the Day What materials can money or coins be made out of?
Metals
Copper
Nickel
Zinc
Paper
Why is it made out of these materials?

3. Properties Two kinds of Properties: Chemical
Changes in structure or element
Physical
Differences that can be visually observed

4. Physical Properties Do not change the chemical nature of matter Color
Density
Odor
Luster
Freezing/Boiling/Melting Pt.
Ductility
Malleability

5. Chemical Properties Changing the chemical nature of matter CombustionpH
Solubility
Electricity (Conductivity)

6. Elements A pure substance Each one on periodic table Each has a symbol
Atomic Weight or Mass
(# of protons + neutrons)
Atomic Number
(# of protons)

7. The Periodic Table

8. Orbitals Red = s Only has 2 e- in it, 0 suborbitals Yellow = p
Has 6 e- in 3 suborbitals
Blue = d
Has 10 e- in it, 5 suborbitals
Green = f
Has 14 e-, 7 suborbitals
All suborbitals only have 2 e- each

9. Electron Configuration
Writing out of all electron orbitals

10. Trends of the Periodic Table
Vertical Columns Called Groups or Families
Horizontal Rows Called Periods
Groups total based on # of electrons
Divided into metals, metalloids & non-metals
Organized by Atomic Number

11. More Trends

12. Other Trends to know Ionization Energy
The amount of energy it takes to pull e- away or add e- to an element
Atomic Radius
How large or small the atom’s nucleus & electron shells are

13. Group 1 Elements 1st Column (Group I)
Alkali - react with H2O to form a basic solution
Hydrogen not a metal but still is part (gas at room temp
All elements have a +1 ion charge
H, Li, Na, K
