Describe the evolution of the atomic model from the billiard ball model to the electron cloud model.

Dalton's billiard ball model-sphere of uniform density. Thomson's plum pudding model-negative electrons dispersed in positive atom. Rutherford's nuclear model- dense, positive nucleus surrounded by negative electrons. Bohr's planetary model-electrons move in circular orbits in specific energy levels. Schrodinger's electrons move within orbital not in specific orbits (Chadwick then added neutrons to the nucleus)

see above
