The Organization of the Periodic Table

  1. Why are the elements in specific places on the Periodic Table?
  2. Periods are ______that run from left to right.
  3. Elements in the same period have the same ______.
  4. Every element in the first period has _____ shell for its ______. Every element in the second period has _____ shells for its ______. Is there a pattern? ______
  5. Groups are ______that run from top to bottom.
  6. The elements of a group have the same number of _____ in their _____ shell.
  7. Every element in group 1 has _____ electron in its outer shell. Every element in group 2 has _____ electrons in its outer shell. (Notice the coloring on the periodic table here – it skips over the middle – the next one that we count as 2 electrons in the outer shell is the one that is colored yellow. What is the first element in this column? ______
  8. Hydrogen is special because it can act like two groups, ______and _____.
  9. Hydrogen sometimes is ______an electron and sometimes it has an ______electron.

Before you continue, number the groups 1-18 and periods 1-7 on your printed copy of the Periodic Table.Color and label the 9 element groups shown on the second web site. You may use the same color scheme or create your own but make sure that you have a legend on the bottom of your periodic table to indicate which color matches which grouping.
