Briefly describe the difference in the Mendeleev’s table and modern periodic table?
Expert
Periodic table is now arranged in the order of raising atomic numbers. Furthermore, it is stated that the modern table makes it simpler to read and learn. The manner that it is set up now permits scientists to make modifications whenever essential.
