32. Positive ions are smaller than the parent ion

33. Metalloids are located On the staircase

34. Metals are located To the left of the staircase (except for H!)

35. Nonmetals are located To the right of the staircase

36. Elements in column 15 (VA) have 5 valence electrons

37. Elements in column 16 (VIA) have 6 valence electrons

38. Trends for metallic character Decreases across. Increases down.

39. Most active metals? Cs & Fr

40. Metals are losers. Reactivity of metals is judged by how easily metals Lose electrons

41. Elements with strongest metallic properties are located In the lower left corner of the periodic table.

42. Periodic table is arranged by Atomic number

43. Electronegativity Ability of an atom to attract electrons in a bond.

44. Most Electronegative Element Fluorine

45. Trends for electronegativity Increases across & decreases down.

46. How do we judge the reactivity of Nonmetals? Nonmetals are winners so we judge the reactivity of nonmetals by how easily they gain electons.
