Far cur purposes wr may consider !t as composed of a central nucleus which carries a positive electrical charge. We may liken an atom to the solar system. This nucleus Is the sun Around this sun a number of electrically charged particles revolve In orbits hi a similar manner to the planets The charges on these particles are all negative and their total value exactly balances the positive charge on the Min or nucleus of theIn the heaviest atoms, such as those ol uranium radium thorium, and several other riullo-actlve elements, the charge 011 Ihe nucleus Is greater than In I lie case of any other element. It apitears that this charge gets a bit too hravv We nil know the way an clec-trli fuse blows out when there Is too much electricity passing through It.
