Mendeleev organized the elements according to their increasing atomic masses and considered their fundamental properties . He also considered the Hydrides and Oxides formed by the elements.
Because he was creating a book called the Principle of Chemistry and he noticed the pattern in every elment. So he made a table or (chart) called Periodic Table of Elements.
Mendeleev created the periodic table of elements. At his time, there was no grouping for the elements. He figured out that they can be grouped by mass and physical properties His result was so good that it correctly predicted elements that were not discovered yet.
Dmitri Mendeleev was the first scientist to create a periodic table of the elements similar to the one we use today. This table showed that when the elements were ordered by increasing atomic weight, a pattern appeared where properties of the elements repeated periodically.
The Periodic Table lists all the elements. In the 1860s Dmitrii Mendeleev organised the elements into a table leaving gaps where he thought elements should be. The modern periodic table is maintained by an organisation called IUPAC, International Union of Pure and Applied Chemists.
those were for the new elements which were yet to be discovered which may be inert in nature. e.g. argon neon krypton etc.

The periodic table is from 1869.

he ordered the elements based on what they're made of.

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.
