What prevented the negatively charged nucleus from pulling the positively charged electrons in and causing the atom to collapse?

Answer 1

The main question that remained after Rutherford's experiment, which Bohr helped to answer, was: What prevents the negatively charged electrons from spiraling into the positively charged nucleus due to electromagnetic attraction, leading to the collapse of the atom?

Rutherford's gold foil experiment demonstrated the existence of a small, dense, positively charged nucleus at the center of the atom, surrounded by electrons. However, classical physics could not explain the stability of the atom, as it would predict that the electrons, being attracted to the nucleus, should lose energy and spiral into it.

Bohr introduced the idea of quantized energy levels for electrons. He proposed that electrons occupy specific energy levels or orbits around the nucleus and that they can only gain or lose energy in discrete amounts (quanta) when transitioning between these levels. This quantization effectively prevents electrons from spiraling into the nucleus, thereby providing a stable structure for the atom.

Answer 2

so whats the answer from what I gave you

Answer 3

The question that remained after Rutherford's experiment that Bohr helped to answer is: What prevented the positively charged nucleus from pulling the negatively charged electrons in and causing the atom to collapse?

This question specifically addresses the stability of the atom in light of classical electromagnetic theory, which predicted that electrons should spiral into the nucleus due to attraction but does not account for the quantized energy levels that Bohr introduced.
