1. NOTES – NOV 27 WRITE IT DOWN

2. An unidentified element has many of the same physical and chemical properties as fluorine and chlorine but has a lower atomic mass than either of these elements. What are the POSSIBLE ELEMENTS that fit the description?

5. The bonding characteristics of Sodium (Na) are most similar to the bonding characteristics of what elements?

8. COLOR in the UNREACTIVE Group (won’t bond with anything)

10. Color in the HALOGENS that form HALIDES

12. COLOR in the group that requires the least energy to form a bond

14. A measure of the ability of a bonded atom to attract electrons to itself is its’?

15. ELECTRONEGATIVITY

18. Write 1 trends that shows INCREASING atomic radii

20. WRITE ANOTHER trend that shows INCREASING atomic radii

22. What is the difference between an ion and an atom?

23. IONS = have a charge ATOMS = neutral

24. How many valence electrons do all ions want?

25. 8

26. If I have 7 valence electrons am I likely to gain an electron or lose the 7 electrons?

27. Easier to gain 1 then lose 7

28. If I have 2 valence electrons….am I likely to gain 6 valence electrons or lose the 2 electrons?

29. Easier to lose 2 then try to get 6 more……

30. How many valence electrons does group 16 have (it is not 16)

31. 6

32. How many valence electrons does group 2 have?

33. 2

34. DO we EVER talk about valence electrons in the middle (transitional metals)?

35. NO....NO….NO…NO…and ….NO (only the FIXED charge groups)

36. SHOULD you ever assume that LIKE Group 3….has 3 valence electrons

37. (the answer is no ….no..no.. no..and no)

38. Which group does not need any more VALENCE electrons ?

39. GROUP 18 (NOBLE GASES)

40. Nitrogen =

41. Nitrogen = Nitride

42. Sulfur =

43. Sulfur = Sulfide

44. Oxygen =

45. Oxygen = Oxide

46. Fluorine =

47. Fluorine = Fluoride

48. Arsenic =

49. Arsenic = Arsenide

50. Iodine =

51. Iodine = Iodide

52. MOST IMPORTANT DO you know the charge of GROUP 1 and 2?

53. MOST IMPORTANT DO you know the charge of GROUP 1 and 2? WHY EVER USE A ROMAN NUMERAL on those groups then…..
