Who proved the plum pudding model wrong?

The plum pudding model hypothesized by Thomson shows the scattering of electrons. When was this discovered in relation to other scientist's atomic hypotheses? After Rutherford but before Chadwick Before Bohr but after Chadwick Before Bohr and Rutherford After Rutherford but before Bohr

Which of the following occurred most recently?The development of the atomic model (which says that all matter is made of tiny, indivisible spheres)The development of the Rutherford modelThe development of the plum pudding modelThe development of the Bohr model2Which of the following statements best describes the plum pudding model?The atom is made up of a ball of positive charge with electrons dotted around inside itThe atom is made up of a ball of negative charge with protons dotted around inside itThe atom is made up of a ball of protons, neutrons and electrons which are spread evenly throughout itThe atom contains positive charge in its centre which electrons orbit around3The Rutherford model is based on the results of the Geiger-Marsden experiment.  In this experiment, alpha particles were directed at a piece of gold foil.  An alpha particle is the same thing as the nucleus of which element?HydrogenCarbonHeliumArgon4Which of the following statements about the Rutherford scattering (Geiger-Marsden) experiment is incorrect?A small number of alpha particles were deflected by small anglesThe experiment was conducted in airMost alpha particles went straight through the gold foilA tiny number of alpha particles (about 1 in 10,000) were deflected by angles of more than 90°5Which of the following is NOT stated by the Rutherford model?Electrons can only orbit the nucleus at specific distancesThe atom is mostly empty space and most of its mass is located in its centre (in the nucleus)Electrons orbit the nucleusThe nucleus and the alpha particle have the same type of charge (positive)6Which of the following statements about the Bohr model is incorrect?An electron can gain energy by absorbing electromagnetic radiationElectrons can only orbit the nucleus at specific distancesWhen an electron loses energy, electromagnetic radiation is emittedThe further away an electron is from the nucleus, the less energy it has
