The chemical symbol of hydrogen is H. It is an element with atomic number 1, this means that 1 proton is found in the nucleus of hydrogen






Hydrogen is the lightest, simplest and most commonly found chemical element in the Universe, making up around 75% of its elemental mass.






Hydrogen is found in large amounts in giant gas planets and stars,



it plays a key role in powering stars through fusion reactions.







Hydrogen is one of two important elements found in water (H2O). Each molecule of water is made up of two hydrogen atoms bonded to one oxygen atom.







In 1766, during an acid metal reaction, Henry Cavendish first formally recognized hydrogen. In 1781 he also found that hydrogen produces water when burned. While Cavendish is usually given credit for the discovery of hydrogen as an element, it had been produced by earlier scientists who were unaware of hydrogen as a unique chemical element.







It wasn’t until a few years later (1783) that hydrogen was given its name. The word hydrogen comes from the Greek word hydro (meaning water) and genes (meaning creator).







Hydrogen gas has the molecular formula H2. At room temperature and under standard pressure conditions, hydrogen is a gas that is tasteless, odorless and colorless
