  1. What we did in class today: Wednesday Feb. 7th, 2011 Reviewed Periodic Table Discussed the different families of the periodic table. Topic Assessment over the periodic table, parts of the atom and metrics.

  2. Which elements had complete outer shells? Give the name and symbol for each. • ________________ _____ ________________ _____ ________________ _____ • What do you notice about the location of these elements? • 2. Which elements had only one valence electron? Give the name and symbol for each. • ________________ _____ ________________ _____ ________________ _____ • What do you notice about the location of these elements?

  3. Alkali Metals Noble Gases AlkalineEarthMetals BoronFamily CarbonFamily NitrogenFamily OxygenFamily Halides 3. What do you notice about the number of valence electrons as you move from left to right across a row or period in the periodic table? Na Mg  Al  Si  P  S ClAr 4. What do you notice about the number of energy levels or shells as you move down a group or column in the periodic table? H  Li  Na

  4. Alkali Metals Noble Gases AlkalineEarthMetals BoronFamily CarbonFamily NitrogenFamily OxygenFamily Halides 5. Write the name of each family at the top of the columns on your periodic table using the following information. 6. What do you notice about the location of the elements in each family?

  5. Alkali Metals Noble Gases AlkalineEarthMetals BoronFamily CarbonFamily NitrogenFamily OxygenFamily Halides 7. In what family would you classify hydrogen? Explain.

  6. Alkali Metals Noble Gases AlkalineEarthMetals BoronFamily CarbonFamily NitrogenFamily OxygenFamily Halides 8. In what family would each of these elements be classified? Radium - ________________________ Tin - ________________________ Iodine - ________________________ Cesium - ________________________

  7. 9. Predict the number of valence electrons for each element based on its location in the Periodic Table of Elements. You will need to use the table in your textbook. Barium = _____ Lead = _____ Bismuth = _____ Potassium = _____

  8. Topic Assessment Label your paper with your name, period and date. Title your paper with Periodic Table Topic Assessment. Number your paper from 1-26. You do not need to skip lines. When you finish, turn it in and begin reading the pages on the whiteboard.
