Is the discovery of the nucleus a real story?
One cannot see an atom in that sense. So this hints that perhaps the story of the discovery of the nucleus was more complicated. The story as it unfolded in Rutherford’s lab at the University in Manchester revolved around real people. It involved frustrations and triumphs.
How did Rutherford and Marsden discover the atomic nucleus?
IN2P3 In 1911, Rutherford, Marsden and Geiger discovered the dense atomic nucleus by bombarding a thin gold sheet with the alpha particles emitted by radium. Rutherford and his students then counted the number of sparks produced by these alpha particles on a zinc sulphate screen.
How did Niels Bohr contribute to the discovery of the nucleus?
From this observation, they concluded that almost all the atomic matter was concentrated in a tiny volume situated at the atome center, the atomic nucleus. The discovery of the nucleus led Niels Bohr to make the first theoretical representation of the atom.
Who was the first person to describe the nucleus of a cell?
Unlike mammalian red blood cells, those of other vertebrates still possess nuclei. The nucleus was also described by Franz Bauer in 1804 and in more detail in 1831 by Scottish botanist Robert Brown in a talk at the Linnean Society of London.
