How was the nucleus discovered?
Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919 Neutron: James Chadwick, 1932
Robert Brown in 1831. Hope this helps! -Zoey Brown
It Was Robert brown,a scottish botanist.
Discovery of the Nucleus Ernest Rutherford, a physicist from New Zealand who was born Aug. 30, 1871, discovered the atomic nucleus.
He conducted the Gold Foil Experiment.
Cell nucleus discovery The question is debatable as Thonius Philips van Leeuwenhoek (October 24, 1632 - August 30, 1723)1, Dutch scientist first observed t…he cell nuleus. "In 1682 he clearly described the nucleus within the red blood cells of fish, and in 1683 he noticed the sedimentation of erythrocytes from a suspension and their lysis upon addition of water."2 It was Robert Brown (December 21, 1773-June 10, 1858)3 a Scottish Botanist who observed and gave the name "cell nucleus". Brown, is best known for the discovery of Brownian motion random movement within fluids due to molecular energy of fluid and also used as a mathematical model for Stochastic processes (random i.e. financial markets, atmospheric events).2,4 Some sources site Brown and not van Leeuwenhoek as the discoverer.5 http://en.wikipedia.org/wiki/Anton_van_Leeuwenhoek1 http://www.bookrags.com/Anton_van_Leeuwenhoek2 http://en.wikipedia.org/wiki/Robert_Brown_(botanist)3 http://www.brianjford.com/wbbrowna.htm4 http://science.discovery.com/convergence/100discoveries/big100/biology.html5
The atomic nucleus (chemistry, physics) - Ernest Rutherford * The cell nucleus (biology) - Antonie van Leeuwenhoek
cell discovery: cell was discovered by Robert hooke in 1665.As he was observing a piece of cork under the microscope he noticed small chambers like honey comb in them.those c…hambers were called cells by ROBERT BROWN.Later another scientist ROBERT BROWN discovered the nucleus in the cell of orchid. A German scientist SHWANN discovered the animal cell with nucleus.
English physicist Ernest Rutherford is credited with discovering the nucleus in the early 1900s. He discovered the nucleus during an experiment in which the physicists bea…med alpha particles at a thin sheet of gold foil. When most of the particles passed through the gold foil onto the screen behind it, but some were deflected, Rutherford determined that the particles that made up the gold foil must consist mostly of empty space. However, he concluded, some regions of the gold must have been too dense to allow the alpha particles through, and this heavy part of the atom was what Rutherford called the nucleus.
In 1911 the existence of the atomic nucleus was discovered by Ernest Rutherford through his interpretation of the gold foil experiment conducted two years earlier by Hans …Geiger and Ernest Marsden. In 1932 Dmitry Ivanenko proposed the proton-neutron model of the nucleus.
Ernest Rutherford (1871-1937) discovered and named the nucleus. Between 1908 and 1913, his assistants Hans Geiger and Ernest Marsden carried out experiments with alpha par…ticles and gold foil. From the results, Rutherford concluded that all of the positive charge (and practically all of the mass) of the atom is concentrated in a tiny fraction of the total volume of the atom. He called it the nucleus (from the Latin for little nut). ------------------------------------------------------------------------------------------------------- Ernest Rutherford discovered that the atom had a nuclius. He was performing an experiment using thin gold leaf (roughly one atom thick) and a source of alpha particles. He used an alpha particle detector to find where they were scattered to by the gold atoms. The then current Thomson "plum pudding" model of the atom predicted the alpha particles would all be scattered through small angles in the forward direction. Rutherford confirmed that the vast majority of the alpha particles were scattered exactly as predicted by that theory. However being a very careful scientist Rutherford tested all angles, including ones where the "plum pudding" model said it was impossible to find scattered alpha particles. Almost all showed no alpha particles as expected, but then he detected a small but very significant number of alpha particles scattering almost directly back to the source that they came from. This was entirely impossible in the "plum pudding" model, and suggested that the atom contained a very tiny hard core containing all the positive charge of the atom, this hard core came to be called the nuclius. His observations in this experiment would be analogous to a macroscopic experiment where you fired artillery shells at a sheet of paper and while most of the shells passed through the paper occasionally one would bounce right back off the paper and hit the artillery piece it was fired from!
