Select Non-Metals: Facts about Hydrogen

Engineers and car manufacturers are researching the possibility of using hydrogen gas as an efficient and viable car fuel.

One of the possibilities involves storing hydrogen as a solid state in car fuel tanks. While there are many challenges involved in this process it would allow for greater hydrogen storage in vehicles, allowing them to travel for longer before refueling.

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 peroxide is a chemical compound with the molecular formula H2O2.

It is often used as a hair bleach or cleaner. At certain concentrations it can also be used to clean wounds.

Hydrogen was used for air travel from 1852 when the first hydrogen lifted airship was created by Henri Giffard. filmed and broadcast live on radio.

Later airships that used hydrogen were called zeppelins and while they were reliable and safe for the majority of the time their use was stopped soon after the Hindenburg disaster in 1937. The Hindenburg airship was destroyed in a midair fire over New Jersey that was both

Hydrogen is used to power a range of new alternate fuel vehicles.

The chemical energy of hydrogen is converted by a combustion method similar to current engines or in a fuel cell which produces water and electricity by reacting hydrogen with oxygen.

In 1766, during an acid metal reaction, Henry Cavendish

first formally recognized hydrogen. In 1781

Hydrogen is found in large amounts in

giant gas planets and stars, it plays a key role in powering stars through fusion reactions.

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

Hydrogen is often stored as a liquid:

in this way as liquid hydrogen takes up less space than hydrogen in its normal gas form. Liquid hydrogen is also used as a rocket fuel.

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.

Hydrogen can exist as a liquid

under high pressure and an extremely low temperature of 20.28 kelvin (−252.87°C, −423.17 °F).

Hydrogen is the lightest, simplest and most commonly found chemical element in the Universe, making up around

75% of its elemental mass.
