  2. There are this many elements in the Periodic Table.

  3. What is 109?

  4. This number of elements comprise just about all living organisms.

  5. What is 4?

  6. This is the most abundant element in our atmosphere.

  7. What is Nitrogen?

  8. Of the 109 known elements, this many are “naturally occurring.”

  9. What is 90?

  10. Those elements not found in nature are made by this process.

  11. What is high energy atomic accelerators and nuclear reactors?

  12. This property means that you could be breathing air that Hitler breathed.

  13. What is the Recycling of atoms?

  14. It takes about this long for one of your breaths of air to become evenly mixed in the atmosphere.

  15. What is 6 years?

  16. This microscope must be used to view atoms.

  17. What is an electron microscope?

  18. This man studied pollen grains under a microscope.

  19. Who is Robert Brown?

  20. This is the phenomenon that Brown discovered by studying pollen and dust particles and their constant state of motion.

  21. What is Brownian Motion?

  22. This is the symbol for an oxygen molecule.

  23. What is O2?

  24. Matter that is in one of these two states is usually comprised of molecules.

  25. What are the liquid and gaseous states?

  26. This tells the proportion of each kind of atom in a compound.

  27. What is the Chemical Formula?

  28. Based on the chemical formula HOCOCH, how many of each kind of atom is in the compound?

  29. What is 2 hydrogen, 2 oxygen and 2 carbon?

  30. Salty water is not a compound due to this factor.

  31. What is the imbalance in the proportion of salt to water throughout the mixture?

  32. This physicist discovered the atomic nucleus by using gold foil bombarded by electrically charged particles.

  33. Who is Ernest Rutherford?

  34. Just about all of the mass of an atom is located here.

  35. What is the nucleus?

  36. This is the reason that electrons are not considered when calculating the atomic mass of an element.

  37. What is very small mass compared to that of a nucleon?

  38. Electrons occupy these as they are added to the atom.

  39. What are electron shells?

  40. This is an isotope of Hydrogen with two neutrons in the nucleus.

  41. What is tritium?

  42. This is the most rare state of matter on Earth, but is the most abundant in the universe.

  43. What is the plasma state?

  44. This is the form of plasma used in your house.

  45. What is a fluorescent light bulb?

  46. What one compound is found naturally in three of the four states of matter on the earth?

  47. What is H2O?

  48. These are the parameters that identifies matter in the plasma state.

  49. What are bare atomic nuclei and free electrons?

  50. At this temperature plasma is created from any other state of matter.
