Question:
how could the modern periodic table remove various anomalies of mendeleevs periodic table
Answer:
The Modern Periodic Table could remove various anomalies of MendeleevÂ’s Periodic Table:
a) In the Modern Periodic table elements are arranged in the increasing order of their atomic number, removing the anomaly regarding certain pairs of elements in MendeleevÂ’s periodic table.
b) Atomic number of cobalt is 27and nickel is 28. Hence cobalt will come before nickel even though its atomic mass is greater.
c) All isotopes of the same elements have different atomic masses, but same atomic number; therefore they are placed in the same position in the modern periodic table.
