2. 3.1 Periodic Table

3. Metals-left side Luster, conductors, malleable, ductile, solids Positive ions Main Groups

4. Nonmetals-far right side Dull, insulators, shatter, brittle Negative ions Main Groups

5. Metalloids-middle intermediate characteristics Elements touching black line (except Aluminum) Main Groups

6. Hydrogen Nonmetal 1 valence electron Forms 1 + or rarely 1 - ions

7. Alkali Metals 1 valence electron Forms 1 + ions Found in compounds in nature Very reactive

8. Alkaline Earth Metals 2 valence electrons Forms 2 + ions Found in compounds in nature Not as reactive as the Alkali Metals

9. Transition Metals Most common metals Can have multiple ion charges Relatively non-reactive Chemical reactions result in a color change Mercury is a liquid at room temp STAR THIS ON YOUR PERIODIC TABLE!

10. Boron Family 3 valence electrons Form 3 + ions

11. Carbon Family 4 valence electrons Forms 4 + ions

12. Nitrogen Family 5 valence electrons Forms 3 - ions

13. Oxygen Family 6 valence electrons Form 2 - ions

14. Halogens 7 valence electrons Form 1 - ions Found in compounds in nature Very reactive Bromine is a liquid at standard temp STAR THIS ON YOUR PERIODIC TABLE!

15. Noble Gases 8 valence electrons Most are non-reactive All are gases

16. Inner Transition Metals Lanthanide Series Actinide Series

17. Periodicity Electronegativity- Ability to attract electrons in a chemical bond Atomic Radius- Size of neutral atoms Ionic Radius- Size of ions 1 st ionization energy- Energy needed to pull off one electron Francium, Fr Large radius Low ionization energy Low electronegativity Fluorine, F Small radius High ionization energy High electronegativity

19. Label the following on your periodic table: Trend lines for: electronegativity, ionization energy AND atomic radius Metals Non-metals Metalloids Transition metals Inner transition metals Names of the columns of the main group elements Number of valence electrons in that column Charge in that column
