Yes, there were elements on the first Periodic Table. I believe that there are still elements on the periodic table.
Dmitri Mendeleev, a Russian scientist, is credited with creating the periodic table of elements in the 19th century. He arranged the elements in order of increasing atomic mass and grouped them based on their chemical properties, leading to the development of the modern periodic table.
There are far to many elements following the 6th on in the Periodic Table. Included below is a link to a very nice Periodic table.
The first periodic table was organized by Dmitri Mendeleev in 1869. Mendeleev arranged elements according to their atomic weight and properties, leaving gaps for unknown elements that were later discovered.
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
Dmitri Mendeleev is credited with publishing the first widely recognized periodic table of elements in 1869. He organized the elements based on their atomic mass and predicted the properties of missing elements, allowing for future discoveries.
Russian chemist Dmitri Mendeleev (1834-1907) published the first periodic table of elements in 1869.

Elements in group 18 of the periodic table.
Very different. Each element is unique.
The periodic table, in which the elements are very cleverly arranged in order of various things, such as electronegativity. It is more complicated that it first appears. Google it.
Moseley
Elements with full outer shells, the noble gas elements, are located in the column at the extreme right of the periodic table.
Hydrogen is found at the very top left of the periodic table. It is the first element on the periodic table and it is shown with the atomic symbol H.

The periodic table of elements is all the known elements in the universe to us. For example, Iridium, we don't find much of it on earth, but we find it very frequently in asteroids. Hope this helped!
