Group 1 elements are often referred to as the "alkali metals'.

Only 100grams of sodium cost $7.00 American wich is $10.00 in NZ currancy. Its atomic weight 22.99; melting point 97.8°C; boiling point 892°C; Sodium ranks sixth in abundance out of all the elements in the Earth's crust, which contains 2.83% sodium in combined form. Only oxygen, silicon, aluminum, iron, and calcium are more abundant. Sodium is second after chloride as the most found element in solution in sea water. The important sodium salts found in nature include sodium chloride (rock salt), sodium carbonate, sodium borate (borax), sodium nirate  (Chile saltpeter), and sodium sulfate.
