Dmitri Mendeleev constructed the Periodic Table of elements in 1869 based on Atomic Mass( which is how much an atom weighs). this however was changed many many years later resulting in our current design of the periodic table which is based on atomic number instead.( the number of protons in an atom.)
Dmitri Mendeleev set out the table most frequently used. There are however many other alternate and equally viable tables (See Link)=)

A Periodic table The Periodic Table of the Elements.
Mendeleev developed the periodic table of elements by arranging the elements in order of increasing atomic mass in 1869. He discovered that elements with similar properties occurred in a periodic pattern. He was able to predict the properties of elements that were missing at the time because of this pattern. In 1914, Moseley contributed to the periodic table by reorganizing the elements according to atomic number.
periodic table is an arrangement of elements. Thiamin is not an element and hence not on the periodic table.
Elements are found on periodic table. Compounds are not present on periodic table. The table does not contains mixture.Elements can be found on a periodic table. Compounds can be made by bonding two or more elements. But they are not depicted on the periodic table.
There are 53 Elements in the Periodic Table.

A Periodic table The Periodic Table of the Elements.
atomic number
Russian chemist Dmitry Mendeleyev constructed the original periodic table about 1870. He arranged his table by grouping the similarities of the various elements.
It is called the Periodic Table of Elements.
By grouping the elements on the Periodic Table.
See the link below fot the IUPAC model of the periodic table of elements.

Yes, there were elements on the first periodic table. I believe that there are still elements on the periodic table.
