Answer:

Explanation:

(i) The Modern Periodic Table was classified on

the basis of atomic number. All isotopes of the

same elements have different masses but same

atomic number. Therefore, they occupy the same

position in the Modern Periodic table.

(ii) When elements are arranged according to their

atomic numbers, the anomaly regarding certain

pairs of elements in Mendeleev’s Periodic Table

disappears e.g. atomic number of cobalt and

nickel are 27 and 28 respectively. Therefore,

cobalt will come first and then nickel, although

atomic mass of cobalt is greater.
