Atomic Mass: 22.99 amu Atomic Number: 11 Melting Point: 97.72 C Boiling Point: 883 C Density: 0.971 g/cm3 Parents: Sir Humphrey Davy Birth Place: EnglandBirth Date: 1807Gender: Alkali Metal
Sodium
Positive Attributes: Metallic sodium is vital in the manufacture of esters and in the preparation of organic compounds. The metal may also be used to improve the structure of certain alloys.Negative Attributes: Sodium is potentially explosive in water (depending on quantity) and is a caustic poison, since it is rapidly converted to Sodium Hydroxide on contact with moisture. Compounds: 1.) Sodium Chloride makes common table salt2.) Soda Ash is made up of sodium, carbon, and oxygen.3.) Baking Soda is made up of hydrogen, sodium, carbon, and oxygen. Chemical Description:Valence Electrons: One Ion: Na+1 Oxidation Number: +1Reactivity: Very Reactive

Rubidium Rubidium was born in 1861 by Bunsen and Kirchoff in the mineral lepidolite by use of the spectroscope. Gender: MetalPhysical: 37 Protons, 37 Electrons, 48 Neutrons.Density: 1.532 g/cm3 Boiling point: 688 C Melting point: 39.3 C Specific Heat: . 363J g-1 K-1 Heat of vaporization: 72.216 kJ mol-1 Chemical Description: 1 Valence electron, ion +1, oxidation number: 1, Very reactive.Compounds: Halides, oxides, sulfides.Positive Attributes: carries small amounts of nutrients to the bodies organs. Negative Attributes: Women who are nursing or pregnant should, as a precaution, refrain from taking rubidium supplements unless having first talked with their physician.

CesiumParents: Gustav Kirchhoff Birth Place: Durkheim Birth Date: 1860 Gender: Alkali MetalProtons: 55Electrons: 55Neutrons: 78Symbol: Cs
Atomic Mass: 132.91 amuAtomic Number: 55 Melting Point: 28.5 C Boiling Point: 678.4 CDensity: 1.873 g/cm3
CesiumPositive Attributes: Can be used as a catalyst in the hydrogenation of certain organic compounds. Also removes air traces in vacuum tubes.Negative Attributes: Liquid at room temperature.
Chemical Description:Valence Electrons: One Ion: Cs+1 Oxidation Number: +1Reactivity: Very Reactive
Compounds: 1.) Cesium Graphite where the metal atoms position themselves between the planes of carbon atoms in the graphite crystal structure. 2.) Cesium Nitrate is used as oxidizer to burn Silicon in infrared flares like the LUU-19 flare. 3.) Cesium Fluoride is widely used in organic chemistry as a base.

Francium Francium was born in 1939 by Mlle. Marguerite Perey of the Curie institute, Paris. Gender: MetalPhysical Description: 87 Protons, 87 Elections, 136 Neutrons Boiling point: 677 C, Melting point: 27 CChemical Description: 1 Valence electron, +1 ion, 1 oxidation number, Very reactive. Because Francium is so rare its chemical and physical properties are not known.
