Detailed explanation-1: -According to J.J Thomson, the atom can be divided into its subatomic particles i.e., electrons, protons and neutrons.

Detailed explanation-2: -Rutherford’s discovery is now often described as ‘splitting the atom’ in popular accounts, but this should not be confused with the process of nuclear fission discovered later in the 1930s. Between 1914 and 1919 Rutherford conducted many experiments at the University by bombarding nitrogen gas with alpha particles.

Detailed explanation-3: -Plum Pudding Model of Atom (1904) Thomson was the pioneer to have suggested that the atom is not the most basic unit of matter but an entity that can be further divided into sub-atomic matter.

Detailed explanation-4: -In 1897 Thomson discovered the electron and then went on to propose a model for the structure of the atom. His work also led to the invention of the mass spectrograph.

Detailed explanation-5: -To explain the neutrality of atoms, Thomson proposed a model of the atom in which negative electrons are scattered throughout a sphere of positive charge. He called his atom the plum pudding model.
