Dalton’s atomic model
John Dalton was an English scientist who proposed the first modern atomic model. He proposed that all matter is made of atoms, which are indivisible -
Thomson’s atomic model
Thomson proposed that atoms had small negative particles floating above a fluid of positive charge. This model is also known as the plum pudding model. -
Rutherford’s atomic model
Rutherford proposed that the atom contains a nucleus, with all the positive charges concentrated in the centre. In the model, the electrons were orbiting around the centre. -
Bohr’s atomic model
According to Bohr, electrons can only travel in certain orbits, depending on their energy level, and they can move up and down the orbits releasing or absorbing energy. -
The quantum atomic model
The quantum atomic model is the most detailed model so far of how the atom is composed and how it works. It was developed with contributions by Erwin Schrödinger, Werner Karl Heisenberg, and Louis de Broglie.
The quantum model proposes that matter can behave as waves and that electrons move around the atom in orbitals.
