Hydrogen (H) is the lightest and most abundant chemical element in the universe. With an atomic number of 1, it has a low atomic mass of 1.008. At standard conditions, it exists as a colorless, odorless, tasteless, and highly combustible gas. It consists of diatomic molecules with the formula H_{2}.

Physical Properties

• Melting point: −259.16°C, −434.49°F, 13.99 K
• Boiling point: −252.879°C, −423.182°F, 20.271 K
• Density: 0.000082 g/cm³

Chemical Properties

• Reaction with X_{2} (halogens): Produces hydrogen halides (HX)
• Reaction with O_{2} (dioxygen): Forms water
• Reaction with N_{2} (dinitrogen): Forms ammonia
• Reaction with metals: Produces metal hydrides

Uses

• Ammonia synthesis: The most significant use, where hydrogen reacts with nitrogen to produce ammonia.
• Catalytic hydrogenation: Hydrogen is used to extract solid fats from vegetable oils.
• Rocket fuel: Hydrogen is used in combination with oxygen as a rocket propellant.
• Internal combustion engines: Hydrogen can be used as a clean-burning fuel in engines.

Biological Role

• Hydrogen is essential for life, making up most of the water (H_{2}O) in living organisms.
• It forms weak bonds between molecules, giving water its unique properties.

Production

• Laboratory preparation: Hydrogen can be created by reacting zinc with diluted hydrochloric acid.
• Commercial production: Methods include electrolysis of acidified water and steam reforming of natural gas.

Isotopes

• Protium (H): The most abundant isotope with one proton and no neutrons.
• Deuterium (D): An isotope with one proton and one neutron.
• Tritium (T): An isotope with one proton and two neutrons.
