List the anomalies of Mendeleev's periodic table which were resolved by the modern periodic law.

(N/A) The anomalies of Mendeleev's periodic table that were resolved by the modern periodic law are as follows:
$(i)$ Position of Hydrogen: Mendeleev could not assign a fixed position to hydrogen because it shows properties of both alkali metals and halogens. The modern periodic law places it based on atomic number.
$(ii)$ Position of Isotopes: Isotopes have the same atomic number but different atomic masses. Mendeleev's table was based on atomic mass,leading to confusion. The modern periodic law,based on atomic number,places all isotopes of an element in the same position.
$(iii)$ Anomalous Pairs: In Mendeleev's table,some elements with higher atomic masses were placed before elements with lower atomic masses (e.g.,Cobalt and Nickel). The modern periodic law,based on atomic number,correctly places these elements in increasing order of their atomic numbers.
