  1. Copy this document, title it “[Your Name] Periodic Table Assignment”
  2. Move it to your personal Chemistry folder.
  3. Complete the assignment as instructed below - type in your answers in a different color font PLEASE.
  4.  
  5. What is a period on the periodic table? How many are there?
  6. Periods are the horizontal rows. There are seven periods.
  7. What is a group on the periodic table? How many are there? The group numbers have a letter associated with them. What do the letters A and B distinguish?
  8. Groups are the vertical columns. There are 18 groups. Each group has a number associated with them. The letter A means they have they same amount of valence electrons (EX: Group IA has one valence electron and so on and so forth). The letter B signifies a transition metal which has inconsistent valence electrons.
  9. What are the characteristics of the following elemental groups discussed in the text?
  10. alkali metals
  11.  
  12. alkaline earth metals
  13.  
  14. halogens
  15.  
  16. noble gases
  17.  
  18. metals
  19.  
  20. nonmetals
  21.  
  22. metalloids
  23.  
  24. Using the Periodic Table of the Elements given to you in class:
  25. Identify the groups of elements called:
  26. alkali metals
  27.  
  28. alkaline earth metals
  29.  
  30. transition elements
  31.  
  32. halogens
  33.  
  34. noble gases
  35.  
  36. Color code these groups on your Periodic Table using colored pencils (make a key) - Color lightly (don’t press hard) and consider lighter colors to start with. Darker colors will be used later.
  37.  
  38. Color Code the following other groups in some creative way (single line around square of color different than one already there) - I recommend using a darker color here.
  39. metalloids
  40. metals
  41. nonmetals
  42.  
  43. What is an isotope?
  44. Define an isotope.
  45.  
  46. Using ptable.com:
  47. identify the common isotopes of carbon and write them here using the chemical symbol, mass and atomic number. In parentheses write the percent abundance for each.
  48.  
  49.  
  50. How many neutrons does C-14 have? C-12?
