The Periodic Table of elements was first created by Dmitri Mendeleev in 1869. He was a Russian chemist who arranged all the elements (known to man at that time period) in order of increasing atomic number. He found that each one resembled the 8th element following it in appearance, properties, and activity.
It was invented by Russian chemist Dmitri Mendeleev in 1869, to classify all elements that were discovered by scientists all over the world.
true but some say it is Johann Dobereiner.
Dmitri Mendeleev.. 1869
A Periodic table The Periodic Table of the Elements.
yes
One thing that could change the periodic table is the discovery of emirical evidence for a "g" sublevel.
who introduced the first 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.
Francium is in the period 7 and group 1 of the periodic table (alkali metals).
A Periodic table The Periodic Table of the Elements.
That is what is claimed.
atomic number
yes
It is quite possible that newly-discovered elements may be added to the periodic table in the future.
solid
Technetium is placed in the group 7 (manganese group) and period 5 of the periodic table of Mendeleev. The atomic number is 43.
the answer to your question has finally come!! the elements of the Periodic Table are mostly some of the items we have used for centuries at a time. for the other that are not, i cannot answer for you.

A group in Periodic Table is the column of element in periodic table
If you are talking about Dmitri Mendeleev, he was the first to come up with the first periodic table and the periodic law.
