Scientist Bohr modified this model. He said that the electrons cannot orbit the proton in any kind of orbit. They had to orbit them in special orbits, a fixed distance from the nucleus. For example, no electron can be found at Point A in Figure 1.
Which of the following is similar to the electron's orbit?
  • A merry-go-round (Figure 2)
  • A spiral (Figure 3)
  • Both
  • Neither
