Question

What is the main difference between the Bohr model and the electron cloud model of the atom.

Answer 1

In the Bohr model, an electron’s position is known precisely because it orbits the nucleus in a fixed path.

In the electron cloud model, the electron’s position cannot be known precisely. Only its probable location can be known.

Answer 2

Answer: The main difference between the two models was about the location of the electron in an atom.

Explanation: Bohr in his model described that the electrons are revolving around the nucleus in discrete circular paths known as shells or orbits. He was not able to explain the exact or probable location of the electrons in an atom.

But, Electron cloud model which was given by Erwin Schrodinger explained the probability of finding an electron in an atom by using the emission spectra of that atom.

Hence, the main difference between these two models was on the location of electron in an atom.
