  1. Periodic Table Flashcards

  2. Group or Family Column (up & down)

  3. Period or Series Row (across)

  4. # of valence electrons Elements in the same column have the same …

  5. # of principle energy levels Elements in the same row have the same …

  6. the number of valence electrons Chemical properties are determined by

  7. one valence electron Elements in column 1 (IA) have

  8. two valence electrons Elements in column 2 (IIA) have

  9. Noble gases The name of the family in column 18 (VIIIA)

  10. Halogens The name of the family in column 17 (VIIA)

  11. H2, N2, O2, F2, Cl2, He, Ne, Ar, Kr, Xe, & Rn Elements that are gases at room temperature

  12. Hg (metal) & Br2 (nonmetal) Elements that are liquids at room temperature

  13. Chemical properties Elements in the same column have similar

  14. 3 valence electrons Elements in column 13 (IIIA) have

  15. 4 valence electrons Elements in column 14 (IVA) have

  16. Half the diameter of an atom, a measure of size Atomic radius

  17. Increases as you go down a column (more principle energy levels) & decreases across a row (greater effective nuclear charge) Trends for atomic radius

  18. Alkali Metals Name of family for column 1

  19. Alkaline Earth Metals Name of family for column 2

  20. Amount of energy required to remove the most loosely held valence electron from a gas phase atom Ionization Energy

  21. X + energy  X+ + e- Ionization

  22. Decreases as you go down a column, increases across a row Trends for Ionization Energy

  23. LOSERS Metals are “_______”

  24. Positive ions Metals lose electrons to form …

  25. Properties of metals Malleable Ductile Good conductors of heat & electricity Lustrous Low ionization energy Low electronegativity

  26. Properties of nonmetals Opposite of Metals Brittle Dull Poor conductors of heat & electricity High ionization energy High electronegativity

  27. winners Nonmetals are “_______”

  28. Negative ions Nonmetals gain electrons to form …

  29. High ionization energies & high electronegativies Nonmetals have

  30. low ionization energies & low electronegativies Metals have

  31. Negative ions are Larger than the parent ion

  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.

  47. Trends for nonmetallic character Increases across and decreases down.

  48. Elements in column 17 (VIIA) have 7 valence electrons

  49. Elements in column 18 (VIIIA) have 8 valence electrons

  50. Form brightly colored salts and solutions (except Zn) Transition metal ions
