It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
including "unknown elements" there are 59 elements in half of the periodic table, not including them there is 55.5 Added: 92 natural elements/2 = 46 natural elements make up 1/2 periodic table.
The periodic table of elements was created by Dmitri Mendeleev, a Russian chemist, in 1869. He arranged the elements based on their atomic mass and properties, and left gaps for elements that were yet to be discovered. Over time, new elements were discovered and added to the periodic table by various scientists.
There are 53 Elements in the Periodic Table.
118 elements are in the periodic table of elements; some of them are still unnamed (January 2013).
Elements have been and still are being added
There were 103 elements on the periodic table in 1968.
1950
you find the ones that have been added to the periodic table in the old days

There are 53 Elements in the Periodic Table.
As new elements were discovered and added to the periodic table, the elements were arranged based on their increasing atomic number and similar chemical properties. This resulted in new rows being added to accommodate the additional elements, expanding the table's size and complexity. The periodic table evolved to its current form with the addition of new elements and improvements in our understanding of atomic structure.
Elements of the Periodic Table
The system of the Periodic Table is not changed after the addition of a new element.
