  b. There is no gravitational force within atoms, because the law of gravitation applies only to large objects.
  c. Atomic particles have too little mass for gravitational attraction to compete with electric forces.
  d. At large distances, individual charges have essentially no effect since, overall, atoms are electrically neutral.
  e. Both c. and d.
