Both oxygen and hydrogen are reactive, colorless gases that are found in the air and are essential for your survival. The primary difference between the two elements is their physical and chemical properties.
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 (H 2 O). 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.ydrogen can exist as a liquid under high pressure and an extremely low temperature of 20.28 kelvin (â252.87Â°C, â423.17 Â°F). Hydrogen is often stored 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.
