=Sodium =

  Say What?  “soda” means “headache remedy”. Its element symbol comes from the Latin word, natrium, which stands sodium carbonate     What is sodium?

-Sodium was first isolated by Sir Humphry Davy in England -Sodium is never uncombined in nature      -Sodium has the atomic number of 11 and the mass of 22.9898 g/mol -Sodium is in the group, 1A, which is all of the alkali metals -Sodium is really common. It is the 6th most abundant element on earth -It is silvery white and is a highly reactive element -There are 18 isotopes of sodium, and all of them are radioactive -Melting point: 370.95 K (208.04°F) -Boiling point: 1156 K (1621°F) -Sodium is mostly found as sodium chloride (table salt), and sometimes found as sodium carbonate and sodium sulfate -Sodium is solid at room temperature

Cost?

-Metallic sodium is 15-20 cents/lb. It is the cheapest of all elements

   What are its uses?
