WebThe modern periodic table lists the elements in order of increasing atomic number (the number of protons in the nucleus of an atom). Historically, however, relative atomic masses were used by scientists trying to organise the elements. This was mainly because the idea of atoms being made up of smaller sub-atomic particles (protons, neutrons and ... WebAs the modern periodic law is based on the atomic numbers of elements, all the anomalies of Mendeleev\'s periodic table were removed. For example: The position of isotopes could be explained, which Mendeleev\'s periodic table failed to explain. As all the isotopes of an element have the same atomic number, so they could be placed under the same ...
WebIt was Henry Moseley who demonstrated that atomic number of an element could explain periodic properties in a better way than atomic mass of an element and arranged the elements in increasing order of their atomic numbers. Then it was found that the various anomalies of Mendeleev's periodic table were removed by the modern periodic table.
