4. The Periodic Table Organized by increasing atomic number
Periods: The rows (1 through 7)
Groups/Families: The columns (1 through 18)

5. Label Your Periodic Table!
Label the periods and groups of your periodic table handout (2 min) 18 1 1 2 13 14 15 16 17 2 3 4 5 6 7 8 9 10 11 12 3 4 5 6 7

6. Metals Shiny Solid at room temperature Conduct heat and electricity
Malleable and ductile

7. Alkali Metals Group 1 (except hydrogen)
Extremely reactive – found in compounds with other elements
Extremely soft (can cut with a knife)
Example: sodium (Na) is found in table salt

8. Alkaline Earth Metals Group 2 elements Highly reactive
Softer than most metals except the alkalis
Example: Calcium (Ca) is used in muscle contractions

9. Transition Metals Groups 3-12 Create color in many compounds
Can have magnetic properties
Example: Iron (Fe) is used in construction because it is strong

10. Inner Transition Metals
Two sets at the bottom of the table
Lanthanide Series (top)
Actinide Series (bottom)
Example: Elements in the Lanthanide series are used as phosphors (emit light when hit with electrons)

11. Non-Metals Typically gases or dull solids
Poor conductors of electricity and heat
Very important in living organisms

12. Halogens
Group 17
Highly reactive – bad for living creatures in high doses
Examples: chlorine in swimming pools

13. Noble Gases Group 18 Extremely unreactive Colorless, odorless
Example: Neon gas is used to light up neon signs

14. Metalloids Border between metals and non-metals
Have physical and chemical properties of both metals and non-metals
Examples: Silicon is used in both computers and prosthetics

15. Customize Your Periodic Table
This is YOUR periodic table to use throughout the year. Make it pretty and make it your own!
Select a color and color all the metalloids:
B, Si, Ge, As, Sb, Te, Po, At
Select a second color and color all the non-metals
All the noble gases
All the halogens (except for astatine)
H, C, N, O, P, S, Se
Select a third color and color all the metals (remember – hydrogen is NOT a metal)
Label the following groups:
Alkali metals
Alkaline earth metals
Halogens
Noble Gases
Lanthanide Series
Actinide Series
