"All matter is made out of atoms which are indestructible, indivisible, and identical in mass and property."
"Atoms within a given element are all exactly the same size and weight, while the atoms of different elements look—and are—different from one other."
He showed that it was easy to extract negatively charged particles from atoms."
"Energy is transferred in defined quantities. Electrons should ne moved aroun the nucleus but only in prescribed orbits."
"Negative charges are distributed throughout the atom, like currants in a pudding."
"Neon was composed of two different kinds of atoms, and proved the existence of isotopes in a stable element."
"He discovered how to artificially induce a nuclear reaction in a stable element."
"He articulated the movements of electrons in terms of wave mechanics as opposed to particle leaps."
