1. B. Why did Rutherford defer to the idea of many electrons in rings? C. Can Bohr's explain why there are stable orbits without radiating any energy? D. If you were Bohr, what would you say the size of a hydrogen atom? And why? E. Compute the energy of the Hs spectral line, i.e., the second line of the Balmer series predicted by Bohr's model. The line is emitted in the transition from ni =6 to nf =2.
