Across
  1. 5. the arrangement of atoms inside the mineral
  2. 7. mineral group that forms from halogen elements combined with metallic
  3. 8. mineral group that contains compounds of sulfur combined with metals; they tend to be heavy and brittle
  4. 11. mineral group that contains metals combined with silicon and oxygen; largest group of minerals
  5. 13. measures the ratio of the weight of mineral to the weight of an equal volume of water
  6. 14. the color of a finely powdered mineral as obtained by scratching or rubbing the mineral over a plate
Down
  1. 1. measures a mineral's resistance to scratching
  2. 2. mineral group that is made of carbon, oxygen, and metal; they tend to be very soft and easily dissolve in water
  3. 3. mineral group that contains pure chemical elements
  4. 4. the appearance of rough surfaces of a mineral when it breaks randomly
  5. 6. mineral group that contains compounds of sulfur combined with metals and oxygen; they tend to be soft and translucent
  6. 9. the appearance of a mineral in the light.
  7. 10. the tendency of a mineral to break along certain directions yielding smooth, plane surfaces.
  8. 12. mineral group that forms from the combination of a metal with oxygen; they range from dull ores to gems
