Identify the scientist associated with each major contribution to the development of atomic theory. He discovered the electron. He discovered periodic changes in properties of elements when they are listed in order of their atomic weights. He experimented with the deflection of cathode rays by a magnetic field. He carried out experiments, using gold foil, that measured the scattering of positively charged alpha particles by heavy atoms. He proposed that atoms are the basic units of matter. He proposed the model of the atom had most of its mass concentrated in a very small nucleus. He proposed that in a chemical reaction, atoms are neither created nor destroyed. Answer Bank
