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. Web15 de set. de 2024 · The modern atomic theory, proposed about 1803 by the English chemist John Dalton (Figure 4.2. 1 ), is a fundamental concept that states that all elements are composed of atoms.
