How Electrons Behave in an Atom

For a long time, electron revolving around the atom was an accepted idea that was formulated by Bohr. It later became known that the planetary model suggested by Bohr was not true. Now, electrons are assumed to be clouds which is a concept derived from their probabilistic location. This is true but electron does exist as a single entity in the nucleus and just their position (that we get form their clouds) does not give information about how the electrons act in the atom. The proposed hypothesis tells how electrons actually behave in an atom and the result of what happens due to its behavior.
