Chapter 6 Electronic Structure of Atoms
... In the early 1900s, the atom was understood to consist of a positive nucleus around which electrons move (Rutherford’s model). This explanation left a theoretical dilemma: According to the physics of the time, an electrically charged particle circling a center would continually lose energy as elect ...
