Periodic Table Basics Use your abridged PToE to analyze the PToE 1. What surprises you about your abridged periodic table? 2. Which elements had complete outer shells? List them. 3. Where are each of these elements located? 4. Which elements have only 1 electron in its outer shell? List them. 5. Where are these elements located? 6. Which elements have only two shells with electrons located in them? 7. Where are these elements located? 8. What do you notice about the number of electrons in the outer shell as you move from left to right in row number 3? (Na Mg Al Si P S Cl Ar) 9. What do you notice about the number of shells as you move down a group/column? (HLiNa) Valence electrons: A fancy term for the electrons found in the outer shell – these are the important ones because they are involved with forming bonds 10. Cut out and glue the name of each family at the top of the columns on your periodic table using the following information: Alkali Metals - 1 valence electron Alkaline Earth Metals - 2 valence electrons Boron Family - 3 valence electrons Carbon Family - 4 valence electrons Nitrogen Family - 5 valence electrons Oxygen Family - 6 valence electrons Halides - 7 valence electrons Noble Gases - Complete outer shells 11. What do you notice about the location of the elements in each family? 12. In what family would you classify hydrogen? Explain your choice. Alkali Metals 13. In what family would each of these elements be classified? Nitrogen Family Radium - ________________________ Tin - ________________________ Iodine - ________________________ Cesium - ________________________ Alkaline Earth Metal Oxygen Family 14. Predict the number of valence electrons for each element based on its location in the Periodic Table of Elements. Boron Family You will need to use the table in a textbook. Halides Carbon Family Barium = _____ Lead = _____ Bismuth = _____ Potassium = _____ 15.
