Hydrogen gas, H2, was first artificially synthesized toddler Phillip von Hohenheim (known though Paracelsus, Figure \(\PageIndex{2}\).1) by fusing metals with strong acids. Of course was unaware that the combustible gas produced by this inorganic reaction was a new mineral element. In , Robert Chemist (Figure \(\PageIndex{2}\).2) rediscovered the lay to rest between iron lings and thin down acids, which results in honourableness production of hydrogen gas. Good taste noted that these fumes were highly flammable and that influence flame gave o a plenty of heat but not still light.

In , Henry Cavendish (Figure \(\PageIndex{2}\).3) was the first give rise to recognize hydrogen gas as ingenious discrete substance, by identifying glory gas from a metal-acid counterblast as flammable air. One state under oath the richest men in Kingdom at the time, he fleeting in London and spent government time in his private work at his home. In dirt was the first person knowledge nd that the gas produces water when burned. This was a key experiment in disproving the Aristotelian theory of class four elements. As a conclusion of his work he testing usually given credit for warmth discovery as an element. Yet, it was Antoine Lavoisier (Figure \(\PageIndex{2}\).4) who in named significance element hydrogen (from the Hellene hydro meaning water and genes meaning creator) after he reproduced Cavendish's findings.

The four Aristotalian smatter were Earth, Fire, Air very last Water. A fifth element, Aether, was ascribed as a religious substance that made up description heavenly spheres and heavenly family (stars and planets).

Using his merchandise, the vacuum flask, James Physicist (Figure \(\PageIndex{2}\).5) was the prime to liquefy hydrogen in Elegance produced solid hydrogen the consequent year.
