What identifies a flaw in J. J. Thomson’s model of the atom?

The plum-pudding model showed the positive charges in atoms as dense and centrally located instead of as diffused across the atom.

The plum-pudding model did not identify a central nucleus as the source of a positive charge.

The plum-pudding model included a central, positively charged nucleus but lacked information about the location of electrons.

The plum-pudding model only provided a 90-percent probability of each electron’s location.

Sir Joseph John Thomson, most popularly known as J J Thomson. He was a famous scientist who was awarded the Noble prize for Physics for his discovery of the subatomic particle, electron.

He placed his famous model of an atom which is known as plum pudding model. He proposed that the atoms are described as the negative particles that is floating within a soup of the diffuse positive charge.

But the main defect of his proposal was that it did not recognized the presence of a central nucleus as a positive charged source.
