Geskiendenis
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.
