Across
  1. 4. subatomic particles with a negative charge

  3. 8. the smallest possible "piece" of an element
  4. 9. a solution with a pH less than 7
  5. 10. the type of bond that links amino acids to their neighbors
  6. 12. three long hydrocarbon chains (fat)
  7. 14. a solution with a pH greater than 7 (basic)
  8. 16. a pure substance that cannot be broken down by chemical means into other substances
  9. 17. substances which are polar and readily dissolve in water (sugar, salt)

Down
  1. 1. two or more chemically joined atoms
