basically, the new periodic table have more elements than the old one, but there are just two elements that are swapped in the old periodic table.

Old periodic table has 65 elements and new table 118 elements

If new elements are placed, then they would be appended in the periodic table. It won't disturb existing periodic table.

The importance of the periodic table is to help find out where and how new elements might be found.

Mendeleev supposed that a new row is necessary in the periodic table after the discovery of lanthanoides.

No, because as the days and years go past, more scientists will find out more information on the periodic table. When they find out information on the periodic table, sometimes new elements are found, adding new elements on the periodic table causes it to change.

New Periodic Law: Based on atomic numbers Old Periodic Law: Based on atomic weights

The periodic table is never complete because people/scientists find or make new elements, so the periodic table keeps on getting developed. :)

New elements have been discovered or synthesized and added to the periodic table.

Mendeleev created a new row on the periodic table every time chemical properties were repeated.

All the elements on the periodic table are created by stars in our universe. Stars recycle these elements to make new stars and they make new elements. Without stars, there would be no periodic table of elements.

There are 91 metals in the periodic table today, but new ones are added as time passes.

In Mendeleev periodic table elements were arranged in the increasing order of their atomic masses and there were free spaces for the new elements which were not discovered at that time. This periodic table had more periods than groups.In Mosley periodic table elements were arranged in the increasing order of their atomic numbers and there were no free spaces for the new elements which were not discovered at that time. This periodic table has more groups than periods.

Mendeleev periodic table was able to predict the properties of new elements which were discovered later on.

The modern periodic table of the elements was published by Dimitri Mendeleev in 1869. Several new elements have been discovered and added to the table since then.

Many elements remained to be discovered in Mendeleev's time. The periodic table helped predict the properties of new elements. The modern periodic table is used to predict properties and reactions of the elements.

New elements can be added to the end of the table.

Nihonium - The International Union of Pure and Applied Chemistry (IUPAC), has officially approved the names of four new elements to be added to the periodic table. The new elements, Nihonium, Moscovium, Tennessine, and Oganesson, are now officially part of the periodic table, in spots 113, 115, 117, and 118, respectively.

Yes, we will forever be adding new elements to the periodic table as we figure out new ways to make them; however, most of what you see now will stay the same.

Periods in the periodic table represent the number of electron shells necessary to fit all of the electrons. Once you fill the valence shell of an atom, the next electron must go in a new electron shell. This would constitute a new period on the periodic table.

The periodic table of the chemical elements (also periodic table of the elements or just the periodic table) is a tabular display of the chemical elements.Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869, who intended the table to illustrate recurring ("periodic") trends in the properties of the elements.The layout of the table has been refined and extended over time, as new elements have been discovered, and new theoretical models have been developed to explain chemical behavior.

The Russian chemist Mendelev was the founder of the modern periodic table, but many scientists who have discovered new elements have added to it.

The system of the periodic table is not changed after the addition of a new element.
