  1. The Periodic Table • You will need your periodic table for these notes. • Today you get to color in class!

  2. The Periodic Table History of the Periodic Table Mendeleev Mosely

  3. A. Dmitri Mendeleev • Dmitri Mendeleev (1869, Russian) • Organized elements by increasing atomic mass. • Predicted the existence of undiscovered elements.

  4. B. Henry Mosely • Henry Mosely (1913, British) • Organized elements by increasing atomic number. • Fixed problems in Mendeleev’s arrangement.

  5. The Periodic Table I.Organization Metallic Character Rows & Columns Table Sections

  6. Use a marker to show the different characteristics of the table! A. Metallic Character • Metals • Nonmetals • Metalloids

  7. Color your periodic table to show the different sections of the table! B. Table Sections • Representative Elements • Transition Metals • Inner Transition Metals

  8. Lanthanides - part of period 6 Actinides - part of period 7 B. Table Sections Overall Configuration

  9. Show groups and periods on the table! C. Columns & Rows • Group (Family) • Period

  10. The Periodic Table III.Periodic Trends Terms Periodic Trends Dot Diagrams

  11. A. Terms • Periodic Law • Properties of elements repeat periodically when the elements are arranged by increasing atomic number.

  12. A. Terms • Valence Electrons • e- in the outermost energy level • Atomic Radius • First Ionization Energy • energy required to remove an e- from a neutral atom

  13. Use a pen to show increasing atomic radius on the table! B. Periodic Trends • Atomic Radius • Increases to the LEFT and DOWN.

  14. Use a pen to show increasing first ionization energy on the table! B. Periodic Trends • First Ionization Energy • Increases to the RIGHT and UP.

  15. B. Periodic Trends • Which atom has the larger radius? • Be or Ba • Ca or Br • Ba • Ca

  16. B. Periodic Trends • Which atom has the higher 1st I.E.? • N or Bi • Ba or Ne • N • Ne

  17. Use a pen to show the group and period numbers on the table! 1 18 2 13 14 15 16 17 B. Periodic Trends • Group # = # of valence e- (except He) • Families have similar reactivity. • Period # = # of energy levels 3 4 5 6 7 8 9 10 11 12

  18. C. Dot Diagrams • Dots represent the valence e-. • EX: Sodium • EX: Chlorine
