research group uses short bursts of laser light to measure the motion of electrons moving within and among atoms. In the planetary model of the atom, the hydrogen atom can be viewed as having a single electron in a circular orbit with a diameter of approximately 10-10 m. If the average speed of the electron in the orbit is known to be 2,200,000 m/s, calculate the number of revolutions per second it makes around the nucleus.
