ELEMENTS

List of Elements

-Hydrogen

-Lithium

-Sodium

-Potassium

-Rubidium

-Cesium

-Francium

Hydrogen

Symbol: H

Atomic Number: 1

Atomic Mass:1.008


Valence Electrons: 1

-Uses

Great quantities of Hydrogen are required commercially nitrogen fixation.

Used in large quantities in methanol production in hydrodealkylation, hydrocracking, and hydrodesulfurization. Other uses are rocket fuel, welding,producing hydrochloric acid,reducing metallic ores, and filling balloons.


Discovered By: Henry Cavendish

GREATER RESEARCH

Rubidium

Rubidium


symbol:Rb

A #:37

AME:85

VE:1


what is Rubidium used for: it`s used for vacuum tubes as a getter, a material that combines with and removes trace gases from vacuum tubes. It’s also used in the manufacture of photo cells & in special gases. scince it`s easily its easily ionized.it might be used as a propellant in noion engines on spacecraft.
