  1. The Periodic TableReview Who is Mendeleev? How did Mendeleev organize the periodic table?

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

  3. The Periodic Table Who is Mosely? How did Mosely organize the periodic table?

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

  5. The Periodic Table Review

  6. The Periodic Table On the periodic table where are the metals located?

  7. A. Metallic Character Metals found on the left • Metals • Nonmetals • Metalloids

  8. The Periodic Table Where are the non-metals?

  9. A. Metallic Character Nonmetals are on the right • Metals • Nonmetals • Metalloids

  10. The Periodic Table Where are the metalloids ?

  11. Metalloids are between the metals and nonmetals A. Metallic Character • Metals • Nonmetals • Metalloids

  12. A. Metallic Character • Metals • Nonmetals • Metalloids

  13. The Periodic Table Where are the representative elements ?

  14. B. Table Sections • Representative Elements • Transition Metals • Inner Transition Metals

  15. The Periodic Table Where are the transition metals?

  16. B. Table Sections • Representative Elements • Transition Metals • Inner Transition Metals

  17. B. Table Sections • Representative Elements • Transition Metals • Inner Transition Metals

  18. Columns & Rows • Group (Family) • Period

  19. The Periodic Table Periodic Trends

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

  21. A. Terms • Valence Electrons • e- in the outermost energy level

  22. 1A 8A 2A 3A 4A 5A 6A 7A B. Periodic Trends • Group # = # of valence e- (except He) • Families have similar reactivity. • Period # = # of energy levels

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