Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
Dmitri Mendeleev first periodic table is called Mendeleev's periodic table. Elements are arranged according to atomic mass.

He created the first periodic table of elements.
The first periodic table created by Dmitri Mendeleev in 1869 contained 63 elements, not W elements. Mendeleev arranged the elements based on their atomic masses and properties, predicting the existence of undiscovered elements. His work laid the foundation for the modern periodic table, which is organized by atomic number instead of atomic mass.
Dmitri Ivanovich Mendeleyev. Another spelling of his name is Dmitri Ivanovich Mendeleev.
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.
Dmitri Mendeleev created the first periodic table of elements in 1869. He arranged elements by increasing atomic weight and grouped those with similar properties together. Mendeleev left gaps for undiscovered elements and was able to predict the properties of these missing elements.

The first periodic table of elements was created by Dmitri Mendeleev, a Russian chemist, in 1869. He arranged the elements in order of increasing atomic weight and grouped them based on similar properties, leading to the development of the modern periodic table.
Dmitri Mendeleev is credited with creating the first widely accepted periodic table of elements in 1869. He arranged the elements according to their atomic mass and properties, predicting the properties of missing elements and leaving gaps for future discoveries.
