Yes, there were elements on the first Periodic Table. I believe that there are still elements on the periodic table.
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.
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.=
The person credited with making the first periodic table is Dmitri Mendeleev, published officially in 1869. However, he only created the first periodic table similar to the one we use today. Alexandre-Emile Béguyer de Chancourtois was the first person to see the similarities between groups of elements. He made the earliest attempt at a kind of table to sort the elements. This table was called the Vis Tellurque, or the Telluric Helix, and it was published in 1863. Lothar Meyer, a German chemist, had also been working on a table, unknown to Dmitri. However, Lothar's table only included 28 elements. Although he published his work in 1864, you will find very few historians that will tell you that he made the first table, since his was so incomplete at the time. Since you are looking for the first person to PUBLISH a table, the best answer would be Alexandre, but the other two would probably work just as well.
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.
