In simple terms, that assertion is correct, but for those with an expertise in the field, the longer answer to who did it ...

German chemists Otto Hahn, a former student of Rutherford's, and Fritz Strassmann, repeated his experiments over the next four years and by 1938, realised what Fermi had discovered was nuclear fission ...

Rutherford made a series of discoveries ... realised what Fermi had discovered was nuclear fission. Fission sees the nucleus of unstable elements like uranium and plutonium split to release ...

J.J. Thomson — a professor of experimental physics at the University of Cambridge, who in 1897 discovered ... atomic nucleus — was launched, ” Priestley said. In 1932, under Rutherford ...

Decades later, Rutherford’s protegees would discover that the nucleus is made up of particles like protons and neutrons. This 1911 discovery redefined atomic structure and, therefore ...

In Bohr’s picture, the electrons encircling the atomic nucleus (that Rutherford had discovered in 1909) are constrained to specific orbits with quantized energies. The electrons can hop in “quantum ...

When an electron dropped from a high-energy orbit to a lower-energy one, it gave out light with an energy equal to the ...
