How Hydrogen Cars Work | HowStuffWorks

As you might recall from high school chemistry class, ,hydrogen, is the simplest of all elements. An atom of ,hydrogen, consists of a single electron and a single proton. The fuel cell generates electricity by stripping the electrons from the ,protons, and using the electrons to create a pure stream of electricity.

This is the number of ,protons, in each atom. Each element has a unique atomic number. Hydrogen is the first element and has one proton, so it has an atomic number of 1. Gold has 79 ,protons, in each atom and has an atomic number of 79. ,Elements, in their standard state also have the same number of electrons as ,protons,.

Carbon,-12 is the common isotope, with ,carbon,-13 as another stable isotope which makes up about 1%. ,Carbon, 14 is radioactive and the basis for ,carbon, dating . The mass of an element that is numerically equal to the atomic mass A in grams is called a mole and will contain Avogadro's number N A of nuclei.
