The Periodic Table is now ubiquitous within the academic discipline of chemistry, providing an extremely useful framework to classify, systematize and compare all the many different forms of chemical behavior. The table has also found wide application in physics, Biology, engineering, and industry. The current standard table contains 117 confirmed elements as of October 16, 2006 (while element 118 has been synthesized, element 117 has not).
Dmitri Mendeleev generally is credited with the creation of the first periodic table, which charts the chemical elements by atomic number and valence shell electron configuration
The periodic Table is very important
The periodic table is a tabular display of the chemical elements, organized on the basis of their properties. Elements are presented in increasing atomic number. The main body of the table is a 18 × 7 grid, with gaps included in to keep elements with similar properties together, such as the halogens and the noble gases. These gaps form four distinct rectangular areas or blocks. The f-block is not included in the main table, but rather is usually floated below, as an inline f-block would make the table impractically wide. The periodic table accurately predicts the properties of various elements and the relations between properties. As a result, it provides a useful framework for analyzing chemical behavior, and is widely used in chemistry and other sciences.
Although precursors exist, the current table is generally credited to Dmitri Mendeleev, who developed it in 1869 to illustrate periodic trends in the properties of the then-known elements; the layout has been refined and extended as new elements have been discovered and new theoretical models developed to explain chemical behavior. Mendeleev's presentation also predicted some properties of then-unknown elements expected to fill gaps in his arrangement; these predictions were proved correct when those elements were discovered and found to have properties close to the predictions.
All elements from atomic numbers 1 (hydrogen) to 118 (ununoctium) have been isolated. Of these, all up to and including californium exist naturally; the rest have only been artificially synthesised in laboratories, along with numerous synthetic radionuclides of naturally occurring elements. Production of elements beyond ununoctium is being pursued, with the question of how the periodic table may need to be modified to accommodate these elements being a matter of ongoing debate
The periodic table was created in the 19th century as a result of a series of scientists during that time. Mendeleev published the first periodic table in 1869.
The periodic table was created by Dimitri Mendeleev in 1869. He arranged all chemicals according to Atomic Mass. He left spaces for the discovery of other elements.
Lothar Meyer and Dmitri Ivanovich Mendeleev both independently produced very similar versions of the periodic table of elements at around the same time. In 1868, Meyer created an extended table and gave it to a colleague for evaluation. However, it was not published until 1870. This was one year after Mendeleev's periodic table was published.
first made around 1700's and was updated around 1990 and was organized 1870
The first modern Periodic Table was either made in 1066, 1492, or 1871. One of those for sure, but which... im not sure.
But otherwise in 1869.

in 1871

Dmitri Mendeleev Made the first ever Periodic table.

He didn't, his was the first and last
No. Xenon is not the first period of the periodic table. It is placed in the 5th period of periodic table.

Dmitri Mendeleev made the periodic table. He is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.

The periodic table of the elements is not a physical table, it is a concept. It is made out of thought.

Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
Yes, there were elements on the first periodic table. I believe that there are still elements on the periodic table.
No. Xenon is not the first period of the periodic table. It is placed in the 5th period of periodic table.
