Question

How did Niels Bohr change the model of the atom?

Answer 1

Hey mate

your answer is.....

Bohr took the ideas of Rutherford (nuclear model), Planck (quanta), Einstein (photoelectric effect and spectroscopy and created the Planetary Model.

Bohr proposed that electrons were in energy levels (ground state) and absorbed photons of certain frequencies to move to a higher energy level (excited state). Then the electrons would release the photons in quantized amounts to return to ground state. The releasing of the photons is responsible for the line spectra given off by elements when excited.

This idea was totally counter-intuitive and required a new physics.

hope it helps you
