The hypothesis of Thomson's atomic model that was later found to be not true by Niels Bohr is that the atom was made up of uniform spheres of positively charged matter in which electrons are embedded.
That the atom was made up of uniform spheres of positively charged matter in which electrons are embedded.
In about 1900 Thomson proposed the atomic model that atom was made up of uniform spheres of positively charged matter in which electrons are embedded. The atom was a sphere of positive charge surrounded by negative charges lumped up together like in a plum pudding.
In 1903 Niels Bohr and Rutherford proposed a model which explained the scattering of electrons by gold foil that the atoms was made up of empty space and a positively charged nucleus surrounded by an electron in what they called a planetary model.
The reason why the Thomson atomic model was found not to be true by Niels Bohr is that it could not explain the scattering of atoms by the gold foil. In the gold foil experiment, most of the electrons fired at the gold foil passed through the atom but some were deflected showing that the atom was made up mostly of empty space and concentrated at the center.
So, hypothesis of Thomson's atomic model was later found to be not true by Niels Bohr is that the atom was made up of uniform spheres of positively charged matter in which electrons are embedded.
