Modern periodic table and Mendeleevs table
Differentiate between the modern periodic table and Mendeleevs table?
Expert
The periodic table is currently arranged in an order of increasing atomic numbers. In addition, it is believed that the modern table makes it easier to learn and read. The method that it is set up now permits scientists to make modifications if necessary.
