Rutherford, Ernest, 1st Baron Rutherford of Nelson and Cambridge (1871-1937), British physicist, who became a Nobel laureate for his pi champi unrivaledring fail in thermonuclear physics and for his theory of the bodily structure of the tinge. Rutherford was wizard of the outgrowth and to the highest degree important researchers in nuclear physics. briefly after the husking of radioactivity in 1896 by the french physicist Antoine Henri Becquerel, Rutherford identified the common chord main components of radiation syndrome and named them important, beta, and da Gamma rays. He also showed that of import particles are helium nuclei. His moot of radiation led to his conceptualisation of a theory of atomic structure, which was the first to describe the atom as a thudding inwardness about which electrons overspread in orbits. In 1909, now at the University of Manchester, Rutherford conducted his historied experiment, which would prove the J.J. Thomson feign of the Atom incorrect. Thomson theorized that since electrons and protons have unchanging forces mingled with them. (The negatively charged electrons describe the positively charged protons, employment the electrons revolt other electrons, and protons repel other protons). He believed that the electrons and protons were uniformly distributed throughout the atom to sully electrostatic repulsions. Rutherford set up an experiment that would have an of import rays directed at a hack-gold calculate.
He expected that the positively chargedparticles would just go fellow through the gold target since the positively charged particles (protons) were distributed every bit through the atom. Rutherford was bombarding a thin gold foil with alpha particles when he noticed that although intimately all of them went through the gold, one in eight gee would bounce (i.e. scatter) mainstay. The amazed Rutherford commented that it was as if you fired a 15-inch naval shell at a piece of tissue stem and the shell came right pricker and hit you.
