Scientist use the electron cloud model to represent an atom.In the electron cloud model, an atom has two distinct regions-the nucleus and the electron cloud.
The electron cloud
J.J. Thomson is credited with the discovery of the electron in about 1904. He envisioned negatively charged "corpuscles" floating in a positively charged cloud, just like plums in a plum pudding. This was the "plum pudding" model of the atom, and it lasted until Geiger and Marsden conducted their gold foil experiment in about 1909.
It is an inaccurate model, because there is no way to measure the exact mass, path, and charge of an atom
proton in nucleas, electron in regions of most probable location
Dalton's atomic theory or model was accepted despite errors. This is because his theory provided a logical explanation of concepts and led the way to new experimentations.

The Electron Cloud model
The electron cloud model best describes the organization of electrons around the nucleus of an atom.

This model is called the electron cloud model. The dark bands represent regions of high probability of finding electrons, known as electron orbitals. Electrons are most likely to be found in these regions surrounding the nucleus of an atom.
Both the Dalton model and the electron cloud model are representations of the structure of an atom. They both describe the atom as having a nucleus at the center and electrons orbiting around it. However, the electron cloud model introduces the idea of electron probability density clouds instead of fixed orbits.

An electron's exact position cannot be pinpointed.
