The Rutherford atomic model, also known as the planetary model of the atom, is a model of the atom that was proposed by Ernest Rutherford in 1911. Rutherford's model is based on his famous gold foil experiment, in which he discovered that the atom has a tiny, massive nucleus.
Rutherford's model of the atom is as follows:
The atom has a tiny, massive nucleus at its center.
The nucleus contains all of the atom's positive charge and most of its mass.
The electrons orbit the nucleus in circular paths.
The electrons are negatively charged and have very little mass.

Rutherford's model was a major breakthrough in the understanding of the atom. It showed that the atom is not a solid sphere, as was previously thought, but rather a mostly empty space with a tiny, dense nucleus at its center. Rutherford's model also explained why atoms are electrically neutral.
While Rutherford's model is a good general model of the atom, it has some limitations. For example, it cannot explain why electrons orbit the nucleus in fixed paths or why atoms emit and absorb light at specific frequencies. These limitations were later addressed by the Bohr model of the atom and the quantum theory of the atom.
Despite its limitations, Rutherford's model of the atom is still a useful model for understanding the basic structure of the atom. It is taught in schools and universities around the world.

The model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the Sun.
