Why is modern periodic table better than Mendeleev’s periodic table
The periodic table of Mendeleev is built according to the ratio of the ranges of properties according to the atomic number of the element. But the modern periodic table treats atomic number as a practical property that determines the properties of the elements. The modern periodic table corrects the shortcomings of the periodic table.
Why Mendeleev had to reverse the order of some of the elements in his periodic table and describe the effect this had on the modern periodic table
Explain why Mendeleev had to change the order of some of the elements in his periodic table, and tell us what effect this had on our modern periodic table.
