How could the modern periodic table remove
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 ... Web(a) Anomalies of Mendeleev’s periodic table: 1. Elements are arranged in increasing order of atomic number in modern periodic table, thus there was no need for keeping more than one element in one slot. 2. Mendeleev failed to explain the position of isotope whereas the modern periodic table puts them in one place in the same group. 3.
