Across
  1. 1. chemical symbol K,its ions are a vital for normal nerve function in the human body and can be found in many fresh fruits and vegetables
  2. 5. chemical symbol Si, it is often used in clays and stones, but is also found in pure form for circuit chips in computers and cell phones
  3. 7. chemical symbol Cu, it is often used in building for roofing as well as historically for plumbing; develops a green patina as it oxidizes
  4. 8. chemical symbol Ni, it has historically been used to plate iron and brass
  5. 9. chemical symbol Ti, this metal can be cobined with many other metal alloys that produce strong but lightweight metals useful for the aerospace industry
  6. 10. chemical symbol Ar,this noble gas is used as an inert shielding gas in welding and is used in flourescent lighting
  7. 13. chemical symbol O, it makes up 21% of Earth's atmosphere and is constantly replenished through the photosynthesis process
  8. 16. chemical symbol C, it's most common alltropes are graphite and diamonds and it is the 2nd most common element in the human body by mass after oxygen
  9. 17. chemical symbol Co, its bluish gray pigment is often used in jewelry and to impart a blue tint to glass
  10. 18. chemical symbol Ga, it is considered a technology-critical element often found in semiconductors and circuits
  11. 20. chemical symbol Be, it can be used as window material in x-ray equipment and is a relatively stable element
  12. 21. chemical symbol Li, its salts have a mood-stablizing property that makes it have treatment applications for those with bipolar disorder
  13. 24. chemical symbol Mg, this shiny grey metal is prized for its lightness and stength and is less dense than aluminum
  14. 25. chemical symbol Fe, it forms most of the Earth's outer and inner core
  15. 27. chemical symbol Sc,discovered in 1879 in Scandinavia it has historically been classified as a rare Earth element
  16. 28. chemical symbol Br,it is used in commercial pools as a substitute for chlorine and compounds formed by this element are useful fire retardants
  17. 29. chemical symbol S, it historically has been called brimstone which means "burning stone"
  18. 32. chemical symbol F, this highly reactive element is often added to metal ores to lower their melting point for smelting
  19. 33. chemical symbol He, it is the first of the noble gases
Down
  1. 1. chemical symbol P, it's name comes from Greek mythology meaning "glow after illumination" and is a common component in fertilizers
  2. 2. chemical symbol Zn, this metal in combination with copper forms the alloy known as brass; in biology it is an essential mineral in prenatal and postnatal development
  3. 3. chemical symbol Se, it is found in metal sulfide ores where it partially replaces the sulfur. Produced mainly as a byproduct in these refining processes it does still have uses in DC power surge protectors
  4. 4. chemical symbol B, it is often found combined with other chemicals as an additive in fiberglass, used in ceramics or in acidic format for use in fertilizers
  5. 6. chemical symbol Cl, it is a common component in pool disinfectants and is one of the two elements in rock salt
  6. 8. chemical symbol Ne this element as a gas is colorless and odorless, but does exhibit an orange-red glow when placed in an electric field
  7. 11. chemical symbol Kr, like most noble gases it is used in lighting and photography
  8. 12. chemical symbol Na,this silvery white metallic element is one of the two elements found in rock salt and is highly water-soluble.
  9. 14. chemical symbol Ca, it is the 5th most abundant element in the human body and is necessary for protein synthesis and bone formation
  10. 15. chemical symbol As, it is classified as a group-A carcinogen and is often found in car batteries,ammunition, herbicides and pesticides
  11. 17. chemical symbol Cr, this element is the main additive in stainless steel and is prized for its resistance to tarnishing
  12. 19. chemical symbol Al, this metal is prized by the aerospace industry for its resistance to corrosion and low density
  13. 22. The lightest and most abundant element in the universe and has the chemical symbol H
  14. 23. chemical symbol Mn, this element is often found in minerals in combination with iron; when found in the body in large amounts it acts as a neurotoxin
  15. 26. chemical symbol Ge, it was discovered by a German scientist and has uses in fibre-optics and LEDs
  16. 30. chemical symbol N, it makes up 78% of the Earth's atmosphere and is found in ammonia and amino acids
  17. 31. chemical symbol V, this element is used by some ocean algae as an active center of enzymes
