P3+Alkali+Metals

= Alkali Metals=

[|Alkali metals] are found in group one of the Periodic Table. They are a solid. Alkali metals are very reactive and are not in our nature. These metals only have one electron in their outer shell. The Alkali metals tend to be softer than most other metals. Alkali metals can explode if they are exposed to water. The alkali metals include Lithium, Sodium, Potassium, Rubidium, Cesium and Francium.

Physical Properties
1. Have a bitter taste and a soapy touch 2. Turns red litmus paper blue 3. Conducts Electricity

Chemical Properties
1. Reacts with ammonium salts to produce Ammonia gas when heated gently 2. Reacts to Oxygen 3. Lithium reacts with water

Facts
Alkali metals tend to have very low melting points, such as Francium's boiling point is 27.05 degrees Celsius. They get damaged very quickly, even in dry air. It is highly possible that Alkali metals can EXPLODE when exposed to water.

Common Uses
There are a few industrial uses for Alkali metals. Sodium Hydroxide is used to make soap as well as being a helpful drain cleaner. Sodium Chloride is a pest and weed killer. Potassium is often added to table salt. Lithium is commonly used in ceramics, glass, rubber products, dyes and is at times used to help treat manic depression.
