Web10 de ago. de 2024 · Henry Moseley (1887-1915) On August 10, 1915, English physicist, Henry Moseley was killed in action. Moseley ‘s contribution to the science of physics was the justification from physical laws of the previous empirical and chemical concept of the atomic number. This stemmed from his development of Moseley’s law in X-ray spectra. WebIt wasn't until 1932 that James Chadwick was able to prove its existence. Chadwick used a version of Rutherford's experiment, using a sheet of beryllium and a paraffin block instead of gold...
