Dmitri Mendeleev first periodic table is called Mendeleev's periodic table. Elements are arranged according to atomic mass.
Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
Dmitri Mendeleev is considered the father of the periodic table. He created the first widely accepted version of the periodic table in 1869, arranging elements based on their properties and atomic weights. Mendeleev's table laid the groundwork for the modern periodic table.
Mendeleev's first periodic table contained 63 elements. He left gaps for undiscovered elements and predicted their properties based on the patterns of the known elements around them. Mendeleev's table was later expanded to include more elements as they were discovered.
When Dmitri Mendeleev first published his periodic table in 1869, there were 63 known elements listed.

Dmitri Mendeleev is credited with publishing the first version of the periodic table in 1869. He arranged the elements based on their atomic weight and properties, creating a table that predicted the properties of missing elements.
The chemist who first designed the periodic table of elements is Dmitri Mendeleev. He arranged the elements based on their atomic mass and properties, creating a framework that laid the foundation for the modern periodic table.
