  2. $100 Question from H1 How many valence electrons does an atom want to have?

  3. $100 Answer from H1 8

  4. $200 Question from H1 Noble gasses have how many electrons and what charge?

  5. $200 Answer from H1 8 valence electrons, no charge

  6. $300 Question from H1 Sulfur has how many valence electrons and it’s ions have what charge?

  7. $300 Answer from H1 6, -2

  8. $400 Question from H1 Alkaline Earth Metals have how many valence electrons and what charge?

  9. $400 Answer from H1 2, +2

  10. $500 Question from H1 What happens to the atom radius of an atom when it loses an electron and why (be specific)?

  11. $500 Answer from H1 The radius becomes smaller because - Each electron is attracted more strongly to the positive nucleus (protons) -The positive charge of the nucleus is divided among more electrons No change in electron shell!

  12. $100 Question from H2 What is the formula for a compound made of K and Cl?

  13. $100 Answer from H2 KCl

  14. $200 Question from H2 What is the formula of a compound made of Se and Ca?

  15. $200 Answer from H2 CaSe

  16. $300 Question from H2 What is the formula for P and Na?

  17. $300 Answer from H2 Na3P

  18. $400 Question from H2 What is the formula for Mg and N?

  19. $400 Answer from H2 Mg3N2

  20. $500 Question from H2 Assuming a reaction occurs, what would be the formula for C and S?

  21. $500 Answer from H2 CS2 If S has a -2 charge, C must take a +4 Or, knowing CO2 and/or SiO2 form, use the columns

  22. $100 Question from H3 Where are the metals and non-metals found on the periodic table? (left/right)

  23. $100 Answer from H3 Metals: Left Non-metals: right

  24. $200 Question from H3 What elements have no electron affinity or electronegativity?

  25. $200 Answer from H3 Noble gasses Also accepted: column 18 or 8a

  26. $300 Question from H3 Which is more metallic, Calcium or Barium?

  27. $300 Answer from H3 Barium

  28. $400 Question from H3 Which has greater ionization energy, Se or Br?

  29. $400 Answer from H3 Br

  30. $500 Question from H3 Put the following in order from most to least electron affinity: K, Ca, Ga

  31. $500 Answer from H3 Ga, K, Ca

  32. $100 Question from H4 What was the most reactive metal in the lab?

  33. $100 Answer from H4 Magnesium

  34. $200 Question from H4 How was it determined that silver was the least reactive metal?

  35. $200 Answer from H4 The aqueous (liquid, ionic) form (Silver Nitrate) of the metal reacted with all of the metals.

  36. $300 Question from H4 Which of the 4 metals tested would Be least likely to be found as a pure Metal in nature?

  37. $300 Answer from H4 Magnesium

  38. $400 Question from H4 In a new experiment metals A, B and C are tested. A solution of element A reacts with metals B and C A solution of element B reacts with metal C only Which metal is most reactive?

  39. $400 Answer from H4 Metal C

  40. $500 Question from H4 When a metal reacts with a solution Is the metal being oxidized or reduced?

  41. $500 Answer from H4 oxidized

  42. $100 Question from H5 What is the meaning of OIL RIG?

  43. $100 Answer from H5 Oxidation Is Loss (of electrons) Reduction Is Gain (of electrons)

  44. $200 Question from H5 Is the following half-reaction Oxidation or reduction? Ag+ + e- Ag

  45. $200 Answer from H5 Reduction

  46. $300 Question from H5 In the following equation, what is oxidized and what is reduced? Mg + Zn2+  Zn + Mg2+

  47. $300 Answer from H5 Mg is being oxidized, Zn2+ is being reduced

  48. $400 Question from H5 In the following equation, what is the oxidizing agent? What is the reducing agent? 2Ag+ + Cu  Cu2+ + 2Ag

  49. $400 Answer from H5 Ag+ is the oxidizing agent Cu is the reducing agent

  50. $500 Question from H5 • Given the following reactivity series • K > Mn > Fe > Ag • Which reaction will occur? • Fe3+ + 3K  3K+ + Fe • 3K+ + Fe  Fe3+ + 3K
