1. Atomic mass
2. atomic number
3. If you line up element by increasing atomic number in the shape of the Periodic Table, as you go across a period, you will see periodic (known) trends.
4. Row on Periodic Table, 7
5. Column on Periodic Table
6. 18
7a. 6ve-
7b. 2ve-
7c. 7ve-
7d. 5ve-
8a. Ne 8b. Ar &8c. Kr 8d. Th
9. a (Na and Cl)
10. c (C and Pb)
11. In s & p block elements, energy level = row number, d block elements, energy level = row # -1 and f block elements, energy level = row # -2
12. d block elements
13. f block
14. Ca since they both have same number and type (subenergy level) of valence electrons.
15. DO NOT DO
16. Rn
17. Ra
18. one
19. 1st column (counting from left to right on Periodic Table)
20. Not counting the d and block, it is the 7th column (counting left to right on Periodic Table)
21. 2nd column (counting from left to right on Periodic Table)
22. Not counting the d and block, it is the 8th column (counting left to right on Periodic Table)
23. He, Ne, Ar
24. Cs
25. I
26. Ag
27. They have the same number and type of valence electrons
28. AR increases since the valence electrons are in higher energy levels that are farther away from nucleus (lower CF)
29. AR decreases since the valence electrons are more tightly held (higher CF) since the nuclear charge is increasing.
30. Lose of valence electrons
31. Gain of valence electrons
32. Cation (lose valence electrons since CF is low)
33. Anion (gains valence electrons since CF is high)
34. Bottom Left of Periodic Table
35. Top Right of Periodic Table
35a. Good conductors of heat and electricity, Malleable and ductile
35b. Bad conductors of heat and electricity, brittle
35c. Either characteristic (can't tell)
36. DO NOT DO
37. Ca, Al, O
38. Cl, Cu. K
39. Decreasing (CF is decreasing)
40. Increases (CF is increasing)
41. S
42. Rb
43. Ar
44. Alkali metals
45. Noble Gases
46. P
47. Ge
48. K
49. K (1 atom)
50. Be
51. At
52. Rn
53. Cs
54. He
55. Bi
56. Pb, Li, Fr
57. Column 1, Valence electron 1, charge 1+
Column 2, Valence electron 2, charge 2+
Column 3, Valence electron 2, charge 3+
Column 15, Valence electron 2, charge 3-
Column 16, Valence electron 2, charge 2-
Column 17, Valence electron 2, charge 1-
Column 18, Valence electron 8, charge 0
58. Give just the number that relate to correct definition for each word.
7, 3, 5, Magic Number = 15
2, 4, 9, Magic Number = 15
6, 8, 1, Magic Number = 15
Magic Number = 15, 15, 15
