Composition of the Atom

The hydrogen atom is made up of one proton and one electron with no neutrons.

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. Unfortunatlly 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. Aydrogen 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 veichles.
