Tarix
Henry Cavendish was the first to distinguish hydrogen from other gases in 1766 when he prepared it by reacting hydrochloric acid with zinc.
In 1670, English scientist Robert Boyle had observed its production by reacting strong acids with metals.
French scientist Antoine Lavoisier later named the element hydrogen in 1783.

Applications
Liquid hydrogen is used as a rocket fuel.
Hydrogen is commonly used in power stations as a coolant in generators.
Hydrogen's two heavier isotopes (deuterium and tritium) are used in nuclear fusion.
Used as a shielding gas in welding methods such as atomic hydrogen welding.
