What is the difference between the new and old periodic table?
Well, Back when Medeleev made this table, many of the elements were not even discovered yet. He plotted only the elements that he knew on his table. He organized them by increasing atomic weight. He didn't know all the elements so he would put question marks and empty spaces in the spots he thought elements would be and left to be found by other scientist. He happened to be true about the missing elements and that scientist did end up finding these "missing links" of the periodic table and led to the new or modern periodic table. The modern periodic table doesnt have any missing elements and they changed Medeleev's way of organizing the table by increasing atomic weight to increasing atomic number. So the newer form of the periodic table was complete and made it easier to find what elements react better with other elements. This making the modern table became the more efficent table of our time.

Dmitri mendeleev constructed the first periodic table which is?
Wich is the table based on the mass of the element rather the number of protons. Later studies created the new table wich was superior to the old one, describing isotpes better.The old table is also called the periodic table of elements just like the new one.Sometimes it is reffered to it with 'mendelev's table of elements'.
