1. The Periodic Table Review

2. Organization Period- Rows –left to right Group or families- Top to bottom

3. What do they have in common? -Groups- -Periods-

4. Metals Shiny appearance Solid at room temperature (except one) High Density and meting point Malleable Good electrical and thermal conductors

5. Alkali metals Very high reactivity *** video examples Lowest densities of metal Soft metals

7. Alkali Earth Metals Similar properties to rest of metals Fairly reactive. Readily lose two electrons to form a “divalent cation”

8. Non-metal Poor electric and thermal conductors Generally brittle Gain electrons easily

9. Metalloids Common properties of both metals and non metals Example: Silicon possesses a metallic lustre, yet it is an poor conductor and is brittle.

10. Halogens Very reactive non metals How many valence electrons? ____ Especially reactive with alkali metals

11. Noble Gases Not very reactive Stable octet- full outer valence shells Low boiling points

12. Transition metals Start to have more than 8 electrons in outer shells Have properties that can depend on the conditions
