Rutherfords planet like structure was defective and unsatisfactory because_________________?
Correct answer: D. all
- A. Moving e- accelerate towards the nucleus
- B. Continuous spectrum
- C. behavior of electron remain unexplained
- D. all
Explanation
Rutherford's planetary model could not explain why an accelerating electron did not continuously radiate energy and spiral into the nucleus, nor could it explain the observed line spectra. These limitations include options a, b and c, so all of them is the intended choice. Students may choose a alone because electron collapse is the most familiar defect, but it is not the only one.

About Discovery of the Proton
The discovery of the proton follows the study of positive rays, also called canal rays, observed in discharge tubes and later identified as positively charged particles. The work of Goldstein and Rutherford is linked to the proton's charge, relative mass and role in the nuclear model, distinct from the discovery of the electron.
