In the Lewis dot diagram there is one extra electron for all of the elements in the alkali metals. They are all reactive to water and are not found in nature by themselves. But they are found when they are combined with other elements.

Lithium comes from the greek word for stone. ​ In 1817 Johann Arfedson discovered this element by passing an electrical charge through melted Lithium chloride and Spodumene. Lithium can __NOT__ be found in nature. Its atomic number is 3 and its boiling point is 1347 celcius, and its melting point is 181 celcius. Lithium has a total of 3 valence electrons, one in the first shell and two in the second. It is used to make Batteries, Ceramics, and Lubricants.

** (Jeremy Singer)Potassium -** Potassium comes from the latin word Kalium. It was discovered in 1807 by Sir humphrey Davy. Davy found Potassium by the electrolysis of fused potassium hydroxide. Potassium is so active that it never occurs free in nature. It always occurs in compounds, combined with other elements. The atomic number is 19, and the atomic mass 39. Potassium has a melting point of 63.65 Celsius and a boiling point of 774 Celsius. You can find Potassium in glass, soap and fertilizer. ​ **(Zach Lerdal)Sodium** Sodium comes from the latin word nutrium. It was discoved by Sir Humphery Davy in 1807. It's atomic number is 11. Sodium has an atomic mass of 23. It has a melting point of 97.72 celsius and a boiling point of 883 celsius. It is found in medicine and never found alone in nature ​ ​ "Lithium."
