'''Hydrogen''' has 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 popular component in many reactions and molecules. Its most common molecule is H<sub>2</sub>O, or [[water]]. | '''Hydrogen''' has 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.

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 the most common element in the entire universe because it makes up almost all stars (the rest of stars' mass is mostly [[Helium]]).

There are also some Hydrogen barrels in ''[[Halo 2]]'' and ''[[Halo 3]]''. 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 Weapon|nuclear]] power to power buildings and heavy vehicles. | ||
