The Hydrogen Atom Let's look at the simplest example of an atom, the  hydrogen atom . The atom consists of a proton and an electron held together by the  electromagnetic  force  between the positively charged proton and the negatively charged electron. The electron orbits around the proton because it is the lighter particle, sort of like the  earth orbits around the sun, There are, however, big differences in the picture of the  earth going around the sun and the electron going around the nucleus. This is because  protons, neutrons and electrons exist on a length scale so small that quantum mechanics  is required to understand the electron's orbit around the nucleus. We will learn more  about the quantum theory of the atom later. When we add neutrons to the  nucleus  of  1 1 H we can make the  isotopes  of hydrogen.  Here are three common  isotopes  of hydrogen. If we add a
