2.  The alkali metals are the first row of the periodic table.  They are all metals with the exception of Hydrogen  In general they have a shinny silvery color, they are soft, and have low melting and boiling points.

3. Hydrogen(H) Hydrogen is the only element of the Alkali elements that is not a metal. Hydrogen has only one valence electron. Hydrogen is a gas a room temperature It can be used to make hydrogen peroxide Physical Properties: Gas Cannot be seen by human eye. Very reactive

4. 1  [He]2s 1  Lithium has only one valence electron  Lithium is a solid at room temperature.  Lithium is used in batteries  Physical Properties:  It’s a metal  Has a low melting point  Has a low boiling point  Reactive with water and oxygen

5.  [Ne]3s1  Sodium has one valence electron  Sodium is a solid at room temperature  Sodium is used a preservative in meat and dairy products  Physical Properties:  Is a metal  Has a silvery color  Has a small density

6. Potassium(K) [Ar]4s1 Potassium has one valence electron Potassium is a solid at room temperature Potassium is a mineral that is necessary in the human body for healthy function. Physical Properties: Has a dull silvery color Has a low density Has low melting and boiling point Is very reactive with oxygen!

7. Rubidium(Rb) [Kr]5s1 Rubidium has one valence electron Rubidium is a solid at room temperature Rubidium is used in vacuum tube and in electronic materials. Physical Properties: Metal Low melting and boiling point Very soft Is reactive with water and oxygen

8.  [Xe]6s1  Cesium has on valence electron  Is a liquid at room temperature  Cesium is added to the center of light bulbs  Physical Properties:  Silvery color  Soft  Reactive with oxygen

9. Francium(Fr) [Rn]7s1 Francium has one valence electron Francium is a solid at room temperature Francium really has no practical use but it used in lab research. Physical Properties: Silvery color Soft Low melting and boiling point Reacts with oxygen
