How did niels bohr describe electrons in his atomic model? their energies can have any values. their exact positions cannot be known. they have high probability to be found in certain regions. they orbit the central nucleus in discrete paths.

they have high probability to be found in certain regions.

Explanation:

Niels Bohr was the first man to describe the atomic model based on a nucleus made from protons and surrounding that the electrons moving on specific energy levels.

Those levels are more energetic closer to the nucleus and the energy decrease with the distance.

The electrons move, and that's why you can't know its exact position. What you do can know is where the electron cloud is. Closer to the nucleus.
