No. A Russian chemist by the name of Dmitry Mendeelev is generally credited with the first Periodic Table of Elements, in 1869.
The number of elements changes periodically because we as humans have the ability to create elements that do not exist in nature. As we create bigger and bigger ones, they are added onto the periodic table of elements.

Arsenic did not create the first periodic table. The first periodic table was created by Dmitri Mendeleev, a Russian chemist, in the 1860s. Other scientists had organized elements in other ways prior to the invention of Mendeleev's periodic table, but the other methods were criticized and did not catch on.
Stars - by nuclear fusion, by supernova explosions, and by colliding neutron stars.
The developers knew to leave blanks because they knew that when humans will discover elements yet to come or create new elements, so people can update the periodic table so it can be more accurate.
It tells you the known natural elements , and unnatural, of the Earth. This gives insight on how and what things are made of, and for chemists what they can combine to create new elements.
