Chem Week 3: Gold; a transition metal

Gold is a transition metal!
Symbol: Au
Atomic number: 79
Atomic mass: 197 
After reading these interesting facts about gold, I can really see why it is valued as the most precious of metals:
Gold is:
  • the most malleable and ductile of ALL metal
  • one gram may be pounded into ONE square METER (one ounce=3,000 square feet) now thats dense!
  • unaffected by air, moisture & corrosive reagents
  • some gold salts have anti-inflammatory properties & are used to treat arthritis
  • injectable gold is used to reduce pain & swelling in rheumatoid arthritis AND tuberculosis
  • Gold is used in dental crowns & bridges b/c it's malleability means it will conform best to the persons dental bite

that's cool! i didnt know you could inject gold to reduce pain and swelling. i guess gold acupuncture needles are very tonifying. i was surprised to see that 3 of us chose gold as our element. so im gonna change to copper. ;)
