WebRutherford wanted to know about how the charges in an atom were distributed. Thompson's Plum-Pudding Model says that the atom is composed of electrons that are surrounded by a positive charge to balance out the atom.Rutherford wanted to determine if this assessment was true, or if it would have a different outcome. Rutherford used the gold- foil experiment … WebSep 22, 2015 · J.J. Thompson's plum pudding model was devised after the discovery of electron but before the discovery of the nucleus of the atom. Rutherford, who overturned Thompson's plum pudding model proposed that on his experiment (Rutherford model) he discovered that the atom has a tiny, heavy nucleus, which is named as nucleus of the atom.
