Explanations for anomalies in Mendeleev's classification of elements 1. Position of isotopes Since all isotopes of an element have the same number of protons, their atomic number is also the same. And since all isotopes of an element have the same atomic number, they can be put at the same position in the periodic table. 2. Position of anomalous pairs The atomic number of argon is 18 and its mass number is 40 while the atomic number of potassium is 19 and its mass number is 39 . Now, according to the Modern periodic law, elements are arranged in increasing order of their atomic number. So argon, with its lower atomic number, should come first, and potassium, with its higher atomic number, should come later. In a similar way, the position of cobalt and nickel are also justified.
