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.
