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.
