It looks the same as it did when Mendeleev created it. There are no changes made to the table throughout the years because Mendeleev had predicted the correct placement for all of our current known elements.
Because the properties of the elements change in a periodic fashion. In the early versions, when fewer elements were known, the chemically similar elements were thought to occur every eight positions.
The periodic table of the elements is not a physical table, it is a concept. It is made out of thought.
Dmitri Mendeleev made the Periodic table.
He made the first periodic table.
The periodic table is entirely made up of elements.

Elements are found on periodic table. Compounds are not present on periodic table. The table does not contains mixture.Elements can be found on a periodic table. Compounds can be made by bonding two or more elements. But they are not depicted on the periodic table.
The final periodic table was made to remove the limitations of previous models.The final periodic table is arranged in order of increasing atomic number.
