Use information found at http://www.aip.org/history/electron/jjelectr.htm to answer the next five questions. 1. J. J. Thomson declared that "we have in the cathode rays matter in a new state, a state in which the subdivision of matter is carried very much further than in the ordinary gaseous state: a state in which all matter. .. is of one and the same kind; this matter being the substance from which all the chemical elements are built up." He named the matter 1. electrons 2. anions 3. corpuscles 4. subatomic particles 2. In an attempt to illustrate the manner in which the negative particles constructed the atom, Thomson developed the plum pudding model. This theory was disproved by one of his own students, . 1. George Thomson 2. Ernest Rutherford 3. Joseph Larmor 4. G. Johnstone Stoney 5. Philipp Lenard 6. Rose Paget 3. J. J. Thomson coined the term electron. 1. true 2. false 4. From the advent of the vacuum tube, cathode rays could be seen to exhibit properties of both particles and waves. Ultimately, J. J. Thomson proved the electron to be a particle. Albert Einstein thought it a mistake to consider the electron to be uniquely a particle or a wave, but not both at the same time. Further study of electrons did indeed result in proof that electrons were waves. This wave nature of electrons was experimentally indicated by , who shared the 1937 Nobel Prize in Physics with an American from Bell Telephone Labs.
