3. Periodic Table Rows are called periods
Columns are called groups or families
Groups 1, 2, and 13 – 18 are called representative elements
Groups 3 – 12 are called transition elements

4. Specific Names Group 1 – Alkali Metals Group 2 – Alkaline Earth Metals

Inner Transition Metals
Lanthanide Series (57 – 70)
Actinide Series (89 – 102)

8. Metals Nonmetals Generally shiny when smooth and clean
Solid at room temperature
Good conductor of heat and electricity
Ductile
Malleable
Left of stair step line
Generally gases at room temperature
Dull, brittle solids
Poor conductors of heat and electricity
Right of stair step line

9. Metalloids
Has physical and chemical properties of both metals and nonmetals
Touching the stair step line
Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, Polonium, Astatine, Uus, Uuo

10. What do you call a clown who's in jail?
A silicon!

11. Alkali Metals Very reactive
Usually exist as compounds with other elements
React violently with water, stored in oil
One valence electron
Silver in color

12. Alkaline Earth Metals
Also very reactive, but less so than alkali metals
Two valence electrons (full s shell)
Usually found in compounds
Silver in color

13. Transition Elements (Metals)
Loosely bound electrons
Excellent conductivity
Electrons in d orbitals
Usually 2 (or 1) valence electrons
Use d and s electrons to bond
Very reactive
Silvery blue in color at room temperature

14. Halogens Are very reactive Seven valence electrons, need to gain one
Can be found in all three states at room temperature
Solid: Astatine and Iodine
Liquid: Bromine
Gas: Chlorine and Fluorine

15. Noble Gases Extremely unreactive Eight valence electrons Very stable
Used to be called Inert Gases
