Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.
he was the man behind the discovery of periodic table according to the atomic numbers
Most chemists attribute the discovery to Dmtri Mendeleev.
63 elements were in Dmitri Mendeleev's First periodic table 63 elements were in Dmitri Mendeleev's First periodic table
This scientist is the Russian chemist Dimitri Mendeleev.
Dmitri Mendeleev first periodic table is called Mendeleev's periodic table. Elements are arranged according to atomic mass.
Dmitri Mendeleev left gaps in the periodic table to account for elements that had not been discovered yet. He predicted the properties of these missing elements based on the patterns he observed among known elements. This led to the successful discovery of new elements that filled in the empty spaces, validating his periodic table.
Actually, Dmitri Mendeleev formulated the periodic law and published his periodic table of elements in 1869. This table arranged elements by increasing atomic mass and grouped them based on similar properties, predicting the properties of missing elements. It was a significant contribution to the field of chemistry.
Dmitri invented a periodic table in 1869 where he arranged the elements in order of increasing atomic masses.
Dmitri Mendeleev published his periodic table in 1869.
