1 Bell Work Write down the 7 major families on the periodic table and tell which block they are in…..hint look at figure 6.8 page 183.

2 Tour of the Periodic Table

3 OBJECTIVES Understand How the Periodic Table is Organized Learn the 7 Basic Families on the Periodic table

4 What are Main-Group elements? Elements in group 1, 2, and The electron configurations of the elements in each main group are regular and consistent. Four groups within the main-group elements have special names (Alkali Metals, Alkali- Earth Metals, Halogens, Noble Gases).

5 What are Alkali Metals? Elements in Group 1Group 1 React with water to make alkaline solutions The Alkali metals have one valence electron Very reactive

6 What are Alkaline Earth Metals? Elements in Group 2Group 2 Slightly less reactive than Alkali metals Have two valence electrons

7 What are Halogens? Elements is Group 17Group 17 Most reactive group of Non-metals Have 7 valence electrons React with most metals to produce salts. Example: NaCl Sodium(Metal) + Chlorine(Halogen)

8 What are Noble Gases? Elements in Group 18 Most Stable Group Low chemical reactivity Full set of valence electrons(8 electrons) Example: Neon 1s 2 2s 2 2p valence electrons

9 What are Transition Metals? elements in groups 3 – 12. Do not have identical outer electron configurations. Less reactive than Alkali or Alkaline Earth Metals

10 What group is Hydrogen in? In a Group by itself Most common element Can react with many other elements Component of the organic molecules found in all living things.

11 What are Actinides and Lanthanides? Part of the Transition Metals Elements 58-71/lanthanide Elements /Actinides(radioactive)

12 Group Activity Periodic Table Game Follow the Directions on the Whiteboard

13 Statement I (true or false) Correct Explanation Statement II (true or false) # 16 #17 # 18 #19
