  1. Atomic Structure

  2. How any protons does an atom of Sodium contain? A. 23 B. 12 C. 11

  3. Remember that the Number of protons Is equal to the atomic Number on the PT RETRY

  4. Remember this number does not change. RETRY

  5. CORRECT NEXT

  6. How many protons does an atom of bromine contain? • 80 • 35 • 45

  7. Make sure to look at the Smaller number on the PT (Hint: the number that is Not a decimal) RETRY

  8. Look for the number at The top of the PT hanging In the room. RETRY

  9. CORRECT NEXT

  10. How many electrons does an atom of Chlorine contain? • 35 • 18 • 17

  11. Remember that the Electrons are equal To the number Of protons RETRY

  12. Remember you need A negative for every Positive. RETRY

  13. CORRECT NEXT

  14. How many electrons does an atom of Bismuth have? • 209 • 126 • 83

  15. CORRECT NEXT

  16. Remember an atom must Have the same number Of positives and Negatives. RETRY

  17. Electrons have opposite Charges as protons. RETRY

  18. How many neutrons does an atom of Arsenic contain? • 33 • 42 • 75

  19. Remember the mass of the Atom is in the nucleus. What does the nucleus Contain? RETRY

  20. Where is most of the Mass of the atom? What particles are there? These particles have the Same mass. RETRY

  21. CORRECT NEXT

  22. How many neutrons does an atom of Tungsten contain? • 74 • 110 • 184

  23. If you know the protons (atomic number) And the mass number (protons + neutrons), You subtract! RETRY

  24. Subtract the 2 numbers On the PT. RETRY

  25. CORRECT NEXT

  26. What is the atomic number of an atom that contains 8 protons, 8 neutrons, and 8 electrons? • 8 • 16 • 24

  27. Remember these determine The identity of the element. This number does not Change for the element. RETRY

  28. These are an element’s DNA! RETRY

  29. CORRECT NEXT

  30. What is the atomic number of an atom that contains 36 protons, 48 neutrons, and 36 electrons? • 36 • 72 • 84

  31. Protons, protons, protons. RETRY

  32. Not neutrons or electrons. RETRY

  33. CORRECT NEXT

  34. What is the mass number of an atom that contains 6 protons, 6 neutrons, and 6 electrons? • 6 • 12 • 18

  35. Where is the mass of the Atom? What is located in That region? RETRY

  36. P + N RETRY

  37. CORRECT NEXT

  38. What is the mass number of an atom that contains 9 protons, 10 neutrons, and 9 electrons? • 9 • 18 • 19

  39. Which subatomic particle Has no mass? Do not Count it. RETRY

  40. Remember that electrons Have virtually no mass so They aren’t counted in the Mass. RETRY
