  2. Click on a question to begin

  3. Question 1

  4. Try Again • The question is asking about one orbital in the 4p sublevel. How many electrons can an orbital hold? Try Again

  5. Correct! • A 4p orbital can hold 2 electrons. Every orbital can only hold a maximum of 2 electrons that spin in opposite directions. Next Question

  6. Question 2

  7. Try Again • The production of light occurs when an atom loses energy Try Again

  8. Correct! • A line spectrum is created when the electrons of a metal salt fall from a high energy level to a low energy level. Next Question

  9. Question 3

  10. Try Again • Higher shells have higher amounts of energy. Try Again

  11. Correct! • When electron falls from a higher shell to a lower shell there is a loss of energy Next Question

  12. Question 4

  13. Try Again • The outermost electrons are the electrons in the outermost s and p orbitals. Add up the total electrons in the outermost s and p orbitals to get the answer. Try Again

  14. Correct! • Oxygen has 2 s electrons and 4 p electrons for a total of 6 electrons in its outermost level. Next Question

  15. Question 5

  16. Try Again • The s sublevel has 1 orbital and the p sublevel has 3 orbitals. Each orbital can hold up to 2 electrons. Try Again

  17. Correct! • The p sublevel can hold 6 electrons while the s sublevel can hold only 2. Next Question

  18. Question 6

  19. Try Again • Add up the total number of electrons and then find the element with that atomic number. Try Again

  20. Correct! • There are 7 total electrons. A neutral atom of nitrogen, with atomic number 7, would have 7 electrons in a neutral atom. Next Question

  21. Question 7

  22. Try Again • Review the definitions on your notes. Try Again

  23. Correct! • The definition of an orbital is the region where an electron is most likely to be found. Next Question

  24. Question 8

  25. Try Again • C = wavelength x frequency Try Again

  26. Correct! • 3 x 108 = (5.45 x 10-7)v v = 5.50 x 1014 Hz Next Question

  27. Question 9

  28. Try Again • The lowest frequency waves have the highest wavelength. Try Again

  29. Correct! • Red light has the longest wavelength and lowest frequency. Next Question

  30. Question 10

  31. Try Again • The shortest wavelength waves have the highest frequency Try Again

  32. Correct! • Gamma radiation has the highest frequency and lowest wavelength. Next Question

  33. Question 11

  34. Try Again • Electrons behave like a particle and wave, but only move like one of them. Try Again

  35. Correct! • Electrons move like a wave, as all matter does. Next Question

  36. Question 12

  37. Try Again • Amplitude is the distance from the mid point to the highest or lowest point. Try Again

  38. Correct! • B to C shows the distance from a crest to the midpoint. Next Question

  39. Question 13

  40. Try Again • Remember that electrons must have different spins to occupy the same orbital. Try Again

  41. Correct! • An up and a down arrow represent two electrons spinning in opposite directions. Next Question

  42. Question 14

  43. Try Again • The kernel structure should have the last element in the row above, plus the valence shell of electrons. Make sure to have the proper number of electrons overall. Try Again

  44. Correct! • The kernel structure is the ten electrons in Ne plus 7 more. [Ne]3s23p5 Next Question

  45. Question 15

  46. Try Again • E = hv Try Again

  47. Correct! • E = (6.63 x 10-34)(5.78 x 1014) Next Question
