What is the first step in developing the modern day model of an atom?

John Dalton published his ideas about atoms. He thought that all matter was made of tiny particles called atoms, which he imagined as tiny spheres that could not be divided.

J J Thomson carried out experiments and discovered the electron. He made the plum pudding model of the atom. In this model, the atom is a ball of positive charge with negative electrons embedded in it.

Ernest Rutherford did the alpha scattering experiment through which he discovered that the mass of an atom is concentrated at its centre and the nucleus is positively charged. He called it the nuclear model.

Niels Bohr did calculations that led him to suggest that electrons orbit the nucleus in shells. The shells are at certain distances from the nucleus.

James Chadwick found evidence for the existence of particles in the nucleus with mass but no charge. These particles are called neutrons.
