On this page I'll provide comprehensive data for Hydrogen. I hope you profit from it.
Hydrogen Overview
Name Origin
Greek: hydro (water) and genes (generate)
Symbol
H (Hydrogen)Description
Tasteless, colorless, odorless gas. The most abundant element in the universe. Tenth most abundant element in the earth's crust.
Discovery
Discovered By: Henry Cavendish
Year: 1766
Location: England
Sources
Commercial quantities are produced by reacting superheated steam with methane or carbon. In lab work from reaction of metals with acid solutions or electrolysis.
Uses
Most hydrogen is used in the production of ammonia. Also used in balloons and in metal refining. Also used as fuel in rockets. Its two heavier isotopes are: deuterium (D) and tritium (T) used respectively for nuclear fission and fusion.
