13. This alkaline earth metal is used in fireworks and flash bulbs and is present in chlorophyll. Magnesium

14. This low density metal is used extensively in foil, kitchen utensils and wiring. Aluminum

15. The second most abundant element in the earth's crust is used in semiconductors (also a joker in jail). Silicon

16. This non-metal is part of the DNA polymer chain and is used in matches. Phosphorus Allotropes of this element

17. This nonmetal is used in the vulcanization of natural rubber and as a fungicide. Sulfur

18. This gaseous halogen is used in bleach, pools and for water purification. Chlorine

19. This inert gas is the third most abundant gas in the atmosphere. abcdefghijklmnopqstuvwxyz Argon The r is missing or gone. Discharge tube

20. Compounds of this alkali metal are sometimes used by people on low sodium diets. Reacts violently (see below )with water. Potassium + water

21. Compounds of this alkaline earth metal make up limestone, chalk, teeth and bones. Calcium

22. This transition metal is as strong as steel, 45% less dense and maintains properties with temperature changes and although in abundance on earth, is expensive to refine. Titanium

23. This transition metal is used as a coating on water taps and bumpers because of its luster but many of its compounds are carcinogenic. Chromium

24. This transition metal is used in many important alloys including steel. Manganese

25. This transition metal is the main element in steel (also a really pressing thing). Iron

26. This is the transition metal present in Vitamin B12 (also what happens to men as they grow old). Cobalt

27. Transition metal whose ion has a green color. Also $0.05. Nickel

28. This transition metal is used for electrical wiring. Copper

29. Transition metal used in many alloys such as brass and to galvanize steel (also where you pour stale milk). Zinc

30. A metalloid used extensively in semiconductor materials. Its name sounds a little like a flower. Germanium

31. This toxic member of the nitrogen family is used in the manufacture of pesticides. Arsenic

32. This halogen is the only liquid non-metal. Bromine

33. This is the lightest element that does not have any stable isotopes. One of its isotopes is used extensively for medical diagnoses. Technetium

34. This brilliant white metal is an excellent electrical conductor and used in jewelry and tooth fillings. Silver

35. This member of the carbon family has predominantly metallic properties and is used to coat steel in cans for preserving food. Tin

36. This toxic solid halogen is used as an antiseptic. Iodine subliming

37. A heavy alkaline earth element. Despite the toxicity of its salts, one of the salts (sulfate) is used in the "milk shakes" taken by a patient for a gastrointestinal series of X-rays (also what happens to patients when the doctor fails). Barium

38. This rare earth element is used to make the strongest permanent magnets. Neodymium

39. This transition metal is used for incandescent light bulb filaments. Tungsten

40. This silvery white, fairly inert, rare transition metal is used in jewelry and for electrical contacts (also what you might like to do to a big meanie). Platinum

41. Gold This transition metal has often been used as the base for monetary systems and is used in jewelry.

42. The only liquid metal. Used for thermostats and to make amalgams for items such as tooth fillings (also a Greek streeker who wore shoes with wings). Unfortunately very toxic. Mercury

43. This metal is used in the manufacture of storage batteries and X-ray shields. Lead

44. The heaviest nonradioactive element. Bismuth

45. This alkaline earth metal is radioactive and has been used on watch and clock hands (also what police do to wild parties). Radium

46. This radioactive element is used in nuclear reactors and weapons but the most abundant isotope (99.3%) does not undergo fission. Uranium

47. This transuranium element although detected recently on earth must be synthesized from U-238. It is used in nuclear weapons and reactors and is extremely toxic. Plutonium

48. https://uwaterloo.ca/chem13news/periodic-table-project/mobile-apps-0 CHEMISTRY MATTERS!

49. While this quiz is over, it is hoped that you will try to learn more about the elements and the periodic table. Although some students perceive that the main goal of testing is for grading, the primary goal of testing is actually to provide a learning experience. Hopefully, you have learned from this experience. Remember that chemistry is everything that matters (including love)!
