1. Bellringer Bellringer: Element or Compound?
Can be broken down into a simpler substance through chemical means He
Two or more different atoms chemically combined
NaCl
Found on the periodic table

2. Today’s Agenda… Element Quizzes/Bellringer Review Periodic Table
BrainPop on Periodic Table
Review Organizing the Elements WS (Study Pack #5)
Notes on Metals (Study Pack #6)

3. Review How are the elements on the periodic table arranged?
What information can be gained by looking at each element on the periodic table?
What does atomic number and atomic mass differ?
What are the columns on the periodic table called?
What are the rows on the periodic table called?
How do we know if one element is similar to another?

4. Why the table works
Recall that protons and neutrons are in the nucleus and electrons are outside of the nucleus
Electrons explain why some atoms bond to others to create compounds

5. Why the table works
Electrons in the outer part of the atom are called valence electrons
These electrons are shared or transferred when atoms of elements come together to make compounds

6. Why the table works
Elements have different numbers of valence electrons
Valence electrons increase from left to right on the periodic table
Elements in each group (or family) have the same number or arrangement of valence electrons

7. Today’s Goals…
I can describe metals using their physical and chemical properties

8. Metals on the Periodic Table
Left of the zigzag line

9. Physical Properties
What is a physical property?
Hardness
Shininess

10. Physical Properties
Malleability – how well it can be pounded into shapes
Ductility – how well it can be made into wire
Example: Copper is both malleable and ductile

11. Physical Properties Conductors Magnetic State of matter
All are solid except mercury

12. Chemical Properties What is a chemical property?
Reactivity – if and how quickly it combines with other elements and compounds
Some metals react explosively when combined with other elements and compounds

13. Chemical Properties Some metals react with air as rust forms
Some metals tarnish

14. Metals in the Periodic Table
Alkali Metals
Alkaline Earth Metals
Transition Metals
Mixed Group
Lanthanides and Actinides
The metals in these groups have similar properties to each other
Change gradually as you move across the periodic table

15. Alkali Metals
Group 1
Very reactive so they are found only in compounds
Soft and shiny
Could cut them with a plastic knife!
Examples:
Na – found in salt
Li – found in batteries

16. Alkaline Earth Metals Group 2 Also found only in compounds Fairly hard
Grey-white
Good conductors of electricity
Examples:
Mg – once found in flash bulbs
Ca – found in your bones

17. Transition Metals Groups 3-12
Even though they are in different families they are very similar to each other
Contains most of the familiar metals
Hard and shiny
Some have unusual colors

18. Transition Metals Good conductors of electricity
React slowly or not at all with air and water
Examples:
Au – coins and jewelry
Fe – in your body

19. Mixed Group Groups 13-16 Also contains nonmetals and metalloids
Not as reactive as those on the left side
Examples: Al
Lead – automobile batteries

20. Lanthanides and Actinides
At the bottom of the periodic table
Also known as rare earth elements
Soft and malleable
Shiny
High conductivity
Examples:
U – used in nuclear power plants
