What did Rutherford discover and what was his model called? Rutherford's atomic model became known asthe nuclear model. In the nuclear atom, the protons and neutrons, which comprise nearly all of the mass of the atom, are located in the nucleus at the center of the atom. The electrons ar...
Of the four postulates of Dalton's theories, one turned out to be not entirely correct. Which one was it? How did the discovery of electrons make it necessary to change one of Dalton's postulates? Who was John Dalton, and why is he so important to chemistry? What did he "discover" ...
Earlier, Dalton had proposed that atoms are the fundamental constituent of matter; they are indivisible and indestructible. In the day, physicists believed that the Universe was permeated by a material they called ether, which acted as the medium to propagate light. The rationale was that if wave...
