5. (You may need to rewind the video.) Be sure the electron is in the first orbit, the orbit closest to the nucleus. Observe what happens when the mouse clicks on the third orbit from the nucleus. When the mouse clicks in the third orbit from the nucleus something happens just before the electron 'moves' to that orbit. What happens? (Use terms like atom, photon, electron, and energy level )
6. When electron is in the first orbit what must happen for the electron to move to an orbit further from the nucleus?
7. When an electron is in an orbit far from the nucleus, what must happen for the electron to move to an orbit closer to the nucleus?
