Bohr’s model introduced the concept of quantized energy levels and laid the groundwork for modern quantum mechanics, revolutionizing our understanding of atomic behavior.
Bohr’s model proposes that only specific orbits with quantized energy levels are stable for electrons, explaining the stability of atoms.
Bohr’s model suggests that electrons in discrete orbits do not radiate energy, contrary to Rutherford’s prediction of continuous energy loss.
Bohr aimed to address the instability predicted by Rutherford’s model, where accelerating electrons would radiate energy and collapse into the nucleus.
