There have been a lot of changes in atomic theory

Explanation:

When JJ thomson found electron the plum pudding model was created which was proven wrong by his predecessor Ernest rutherford when he carried out his gold foil expirment.

Later in comparison to the absorption spectrum and emission spectrum presented the orbits and shell concept

as time proceeds the theory is proven wrong by Werner Heisenberg uncertainty principle an the electron cloud by Erwin schrodinger that states that the electron are present in orbitals not in orbits or shells, but sub shells that are present in shells
