Web7 de fev. de 2024 · The concept of sub-atomic particles did not exist in the 19 th century. In 1913, English physicist Henry Moseley used X-rays to measure the wavelengths of elements and correlated these measurements to their atomic numbers. He then rearranged the elements in the periodic table on the basis of atomic numbers. WebMoseley’s death helped persuade Britain and other countries to rethink the role of scientists in war. Never again would men and women of Moseley’s scientific ability be called upon to serve at the front. Instead, they would be asked to advance the nation’s cause through research conducted far from the fighting.
