How Was it discovered?
• Cavendish collected it after he created a reaction between Mercury and some acids.
• Hydro=Water
• Genes=Generator
Reactivity
• Very Reactive• 3 Natural Isotopes– Protium– Deuterium (AKA Heavy Hydrogen)– Tritium

Everyday Uses of Hydrogen and its Compounds
• Water• Ammonia• Hydrogen Peroxide• Propane• Methane
Characteristics
• Colorless• Odorless• Electronegativity(pauling scale) –(2.18)• Structural shape- Hexagonal• Very dangerous in some reactions with
oxidants.
Advanced Hydrogen Uses
