'''Hydrogen''' is a chemical element with an atomic number of 1; it is the first element in the Periodic Table and is the lightest with a molar mass of 1.00794 g/mol. It has an atomic radius of 78 pm. In its natural diatomic state, it is a colorless, odorless, tasteless gas. It is a very flammable gas and is the lightest element. Its low atomic number makes it a very common component in many reactions and molecules. | |||
Hydrogen is the most common element in the entire universe because it makes up almost all stars (the rest of stars' mass is mostly [[helium]]). When purely combusted with oxygen, the (chemical equation 2H<sub>2</sub> + O<sub>2</sub> ---> 2H<sub>2</sub>O) it forms water and heat, a very useful reaction with a clean result. | |||
Hydrogen is | Hydrogen gas is used to fuel some [[United Nations Space Command|UNSC]] [[vehicles]], such as the [[M12 Light Reconnaissance Vehicle|Warthog]] and [[M274 Ultra-Light All-Terrain Vehicle|Mongoose]]. As fossil fuels have probably been abandoned, hydrogen is most likely [[Human|humanity]]'s current top power source: A [[UNSC Reactor]] use hydrogen instead of nuclear power to power buildings and heavy vehicles. | ||
