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

2. 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.

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

16. N or Bi Ba or Ne N Ne 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!
B. Periodic Trends
Group # = # of valence e- (except He)
Families have similar reactivity.
Period # = # of energy levels 1 2 18

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