How was the nucleus discovered?

Discovery of the Nucleus . Ernest Rutherford, a physicist from New Zealand who was born Aug. 30, 1871, discovered the atomic nucleus..
The nucleus is the very dense region consisting of nucleons (protons and neutrons) at the center of an atom. Almost all of the mass in an atom is made up from the protons and …neutrons in the nucleus, with a very small contribution from the orbiting electrons. It was discovered in 1911, as a result of Ernest Rutherford's interpretation of the famous 1909 Rutherford experiment performed by Hans Geiger and Ernest Marsden, under the direction of Rutherford. The diameter of the nucleus is in the range of 1.75 FM (1.75Ã10â15 m) for hydrogen (the diameter of a single proton) to about 15 FM for the heaviest atoms, such as uranium. These dimensions are much smaller than the diameter of the atom itself (nucleus + electronic cloud), by a factor of about 23,000 (uranium) to about 145,000 (hydrogen).
English physicist Ernest Rutherford is credited with discoveringthe nucleus in the early 1900s. He discovered the nucleus during anexperiment in which the physicists beamed al…pha particles at a thinsheet of gold foil. When most of the particles passed through thegold foil onto the screen behind it, but some were deflected,Rutherford determined that the particles that made up the gold foilmust consist mostly of empty space. However, he concluded, someregions of the gold must have been too dense to allow the alphaparticles through, and this heavy part of the atom was whatRutherford called the nucleus.
The nucleus was discovered in 1899
The nucleus was discovered by Ernest Rutherford in 1914 with his famous gold foil experiment. From the results of shooting alpha particles (radiation) at a sheet of gold foil …he determined that the atom must be made of mostly empty space with a dense, positively charged center called the nucleus. . This was the official discovery, though really Robert brown originally discovered the nucleus of a cell.
Only after the discovery of cathode rays in a discharge tube, scientists thought about the neutral nature of the atoms. Hence they imagined in different ways. So they proposed… different atom models. Then after the famous alpha particle scattering experiement the idea about the nucleus was introduced by Ernest Rutherford in 1909-1911.
The first solid (if you'll pardon the pun) evidence for the existence of the atomic nucleus was Ernest Rutherford's gold foil experiment.
Rutherford and his gold foil experiment are given the credit for this. When the beta particles bounced off the gold foil more than even the largest margin of error based on cu…rrent atomic knowledge, Rutherford figured that there was something material in the center repelling the heavy particles.
In the exact center of the atom.

No that is not nucleus.It is the cell wall.
