How could the Modern Periodic Table remove various anomalies of Mendeleev’s Periodic Table?
  1. The Modern periodic table is arranged in order of their atomic number. This removes inconsistencies in relation to certain pairs of the elements present in the Mendeleev’s periodic table.
  2. The atomic number of cobalt is 27 and that of nickel is 28. Therefore, cobalt will come before nickel even though its atomic mass is large.
  3. All the isotopes of the same elements contain different atomic mass, but the atomic number. Therefore, they are placed in the same place in this table.
