What did Dimitri Mendeleev discover?
Dmitri Mendeleev devised the periodic classification of the chemical elements, in which the elements were arranged in order of increasing atomic weight.
Why did Dimitri create the periodic table?
He used them to correct properties of other elements such as the valence and also to predict properties of some three elements which were undiscovered by then; by putting them in order according to their atomic weights, he realized that physical and chemical properties were related to their atomic mass.

What is Dmitri Mendeleev’s element?

What was Dmitri Mendeleev contribution to the periodic table?
Mendeleev’s Contribution to the Periodic Table. In 1869, Mendeleev contributed to the world of periodic tables by creating his version of the periodic table listing the most known elements at the time by their ascending atomic mass. The elements were also arranged by how reactive they were.
How did Dmitri Mendeleev arrange the periodic table?
Mendeleev arranged the elements in order of increasing weight and broke them into rows such that elements in each column shared valence, the number of other atoms they combined with, as well as other properties.
What is Dmitri Mendeleev best known for?

Why was Dmitri important to the periodic table?
The table can be used to predict the properties of elements,even those that have not yet been discovered.
How many elements were there in Mendeleev’s periodic table?
There were 60 known elements in 1860 when Mendeleev published his Periodic Table. CIENTISTS HAD IDENTIFIED over 60 elements by Mendeleev’s time. (Today over 110 elements are known.) In Mendeleev’s day the atom was considered the most basic particle of matter.
