If you are talking about Dmitri Mendeleev, he was the first to come up with the first periodic table and the periodic law.



He made flashcards of elements and organized them in order of increasing atomic mass.


Dmitri Mendeleev created the first periodic table according to atomic mass


Dmitri Mendeleev was the first scientist to create the periodic table


Mendeleev arranged elements in order of increasing atomic mass. He found that properties are periodic function of atomic masses. He arranged elements with similar chemical properties together.


The periodic table, which was not totally completed. He left gaps for unknown elements which he predicted would have certain properties.



Mendeleev invented it in 1869.


Dmitri Mendeleev was the first scientist to create a periodic table of the elements similar to the one we use today. You can also see Mendeleev's original table (1869).


Dmitri Mendeleev worked alone while working on the Periodic Table and the Periodic Law. He stayed in close contact with other scientists around the globe, however, and received information and data that they had collected, and added it to his own notes to create a more accurate and agreeable set of data to help him arrange the elements.


Arsenic did not create the first periodic table. The first periodic table was created by Dmitri Mendeleev, a Russian chemist, in the 1860s. Other scientists had organized elements in other ways prior to the invention of Mendeleev's periodic table, but the other methods were criticized and did not catch on.


Because he was creating a book called the Principle of Chemistry and he noticed the pattern in every elment. So he made a table or (chart) called Periodic Table of Elements.


Mendeleev arranged the elements in the order of atomic mass, predicted and left spaces for undiscovered elements using "triads".


Mendeleev created a new row on the periodic table every time chemical properties were repeated.


On 6 March 1869, Mendeleev made a formal presentation to the Russian Chemical Society, entitled The Dependence between the Properties of the Atomic Weights of the Elements, which described elements according to both atomic weight and valence.


The purpose was to create a rational instrument for the organization of chemical elements.


No,its not Dmitri Mendeleev.Dmitri Mendeleev create the first periodic table but mostly it was wrong....he arranged them by the atomic number when it should have been by increasing the atomic number(and ya there's a difference)..the one that rearranged it was Henry Moseley.


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.


He helped create the periodic table but Mendeleev beat him to it.



he ordered the elements based on what they're made of.



Mendeleev was working in St Petersburg in Russia when he first published a periodic table. He never referred to a "periodic table", but always to the "periodic law", because it was his insight and mission to proclaim the periodic classification as expressing a law of nature rather than a mere convenient arrangement of elements.


Mendeleev arranged the elements in order of their increasing atomic masses. He placed them in the groups and periods according to similar chemical properties.
