Originally according to western Oregon universities' site: "brief history of the periodic table" the creators wanted a way to track the elements. Originally it was just the elements found in nature. The man made elements came later and were added to the already widely used table. I don't have WOU'S site for reference but you can find it easily from Google. Or just type in" brief history of periodic table" into you favorite search engine.
Natural elements in the Periodic Table are the building blocks of matter found in nature. They exist due to the formation of atoms through nuclear fusion processes in stars, as well as through other natural processes such as nuclear decay and cosmic ray interactions. These elements are essential for the composition of all physical objects in the universe.
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.
Artificial elements.
The table of elements is called the Periodic Table of Elements. It organizes all known chemical elements based on their atomic number and chemical properties.
Yes, all the elements (natural or artificial) are contained in the periodic (Mendeleev) table of the elements.
There are 118 elements listed in the periodic table.

Yes, there were elements on the first periodic table. I believe that there are still elements on the periodic table.
Russian chemist Dmitri Mendeleev (1834-1907) published the first periodic table of elements in 1869.
118 elements are in the periodic table of elements; some of them are still unnamed (January 2013).
There are 118 known chemical elements in the periodic table, with the most recent element being Oganesson.
