What we have learnt
- Hydrogen is the most abundant element in the universe, found primarily in stars and the sun.
- It has three isotopes: Protium, Deuterium, and Tritium, differing in their neutron counts.
- Hydrogen's versatile uses include ammonia production, oil hydrogenation, and its role as a reducing agent.
Key Concepts
- -- Isotopes of Hydrogen
- Hydrogen has three isotopes namely Protium (¹H), Deuterium (²H), and Tritium (³H), which differ in neutron count and occurrence.
- -- Combustion
- The combustion of hydrogen in oxygen produces water, a highly exothermic reaction.
- -- Reducing Agent
- Hydrogen acts as a reducing agent reducing metal oxides to metals during chemical reactions.
