Web22 de mar. de 2024 · In Mendeleev’s Periodic table, the elements were arranged in the increasing order of their atomic masses. Only 63 elements were discovered during Mendeleev’s time, so he made the arrangement of those 63 elements in his table (which is shown above). Moseley’s Periodic table WebMeyer arranged the elements by their atomic volume, which today is equivalent to the molar volume, defined as molar mass divided by molar density. The correlation with the electronic structure of atoms was made when H. G. J. Moseley showed that the periodic arrangement of the elements was determined by atomic number, not atomic mass.
