  2. The negatively charged particles of an atom

  3. What are electrons?

  4. A particle of an atom that has no charge at all

  5. What are neutrons?

  6. The small central core of an atom

  7. What is the nucleus?

  8. A particle with a positive electric charge

  9. What is a proton?

  10. Two or more atoms joined together by certain forces of attraction called chemical bonds

  11. What are molecules?

  12. What is the nucleus?

  13. What is a Periodic Table?

  14. What is a molecule?

  15. What is a chemical symbol?

  16. What is a chemical reaction?

  17. The abbreviation of an element’s name, sometimes from Latin or Greek

  18. What is the Chemical Symbol?

  19. Are like metals in some ways and like non metals in other ways

  20. What are semimetals?

  21. Elements that hardly ever combine with other elements to form molecules. Helium and neon are examples of this

  22. What are Noble Gases?

  23. Usually shiny, can be bent or stretched, and conduct electricity

  24. What are metals?

  25. Many are gases. Solids are usually dull in color, do not conduct electricity and break easily

  26. What nonmetals?

  27. A shorthand way to describe a compound (Fe2O3)

  28. What is a chemical formula?

  29. The small numbers to the lower right of the symbols (H2O)

  30. What are subscripts?

  31. C12H22O11has this many Oxygen atoms

  32. What is Eleven?

  33. At one time water was thought to be an element. This is why it is not

  34. What is the fact it can be broken down into Hydrogen and Oxygen gas?

  35. A pure substance made up of two or more elements that are chemically combined

  36. What are compounds?

  37. CO2

  38. What is Carbon Dioxide?

  39. H2O

  40. What is Water?

  41. NaCl

  42. What is table salt?

  43. H2O2

  44. What is Hydrogen Peroxide?

  45. C12H22O11
