mLine 4:
Line 4: − − ==Fuel for Vehicles== − The hydrogen [[fuel cell]] is a pioneering form of alternative energy. It is very clean burning, the only by-product of its combustion is pure [[water]]. This would slow down the impact that [[global warming]] is having on the Earth. Unfortunately there are some set backs. The amount of hydrogen needed to fuel a regular sized car would be extremely large and would not be as convenient as a fuel tank is now. Hydrogen is extremely [[flammable]] and the flame is nearly invisible. The chances of a massive fatal explosion in an accident is greater than in one with [[gas]] powered vehicles. − − If hydrogen could be used in cars, it would be important in establishing the [[hydrogen economy]].
Im not an expert, but I can recognise the section on use as a fuel is inaccurate... ive taken it out. Someone who knows what they are talking about can replace it.
==Composition of the Atom==
==Composition of the Atom==
One [[isotope]] of the hydrogen [[atom]] is made up of one [[proton]] and one [[electron]] with no [[neutron]]s. This is called [[protium]]. There is also [[deuterium]], with one proton, one electron, and one neutron, and [[tritium]] with one proton, one electron and TWO neutrons. Tritium is [[radioactive]].

Hydrogen can be found in both [[organic]] and [[inorganic]] compounds (for example, [[hydrocarbon|hydrocarbons]] and metal hydrides, respectively. Scientists have determined that hydrogen is the most common element in the universe. It is an important component of [[water]].
