Across
  1. 2. A technique that is used to separate the components of a mixture based on the tendency of each component to travel or be drawn across the surface of another material.
  2. 4. An element that has both metallic and nonmetallic properties; examples of metalloids include B, Ge, Si, and Te.

  8. 17. a chemical substance formed as a result of a chemical reaction
  9. 20. The majority of elements in the Periodic Table
  10. 22. A technique that can be used to physically separate most homogeneous mixtures based on the differences in the boiling points of the substances involved.

  15. 30. vertical columns of elements
  16. 32. a physical blend of two or more pure substances in any proportion in which each substance retains its individual properties; can be separated by physical means.
  17. 33. a type of change that alters the physical properties of a substance but does not change its composition.
  18. 36. a form of matter that has its own definite shape and volume is incompressible and expands only slightly when heated
  19. 37. a physical property that remains the same no matter how much of a substance is present.
  20. 39. a change from one state (solid or liquid or gas) to another without a change in chemical composition

  23. 42. a percentage determined by the ratio of the mass of each element to the total mass of the compound.
  24. 43. the ability or inability of a substance to combine with or change into one or more new substances.
Down
