Dmitri Mendeleev in 1869
No, Dmitri Mendeleev in Russia developed the first periodic table.
he developed the first periodic table in the increasing order of atomic masses of elements.but after the discovery of isotopesthis periodic table was not consider to be effective.

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.

Mendeleev developed the first periodic table and Mosely later modernized it.
who introduced the first Periodic Table
Mendeleev arranged the periodic table according to increasing atomic mass. This method has been used since he first developed it in the 1800s.
The periodic table was first arranged by Dmitri Mendeleev in 1869. He organized the elements by increasing atomic mass and grouped them based on similar chemical properties. Gaps were left for undiscovered elements, with their properties predicted based on neighboring elements.
Meyer developed a table that was similar to modern periodic table. But his work was published later after Mendeleev.
Yes, there were elements on the first periodic table. I believe that there are still elements on the periodic table.
