Dmitri Medeleev was the initial creator of the Periodic Table. But, the most up to date Periodic Table was revised by a British scientist named Henry Moseley.
He is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.
Russian chemist Dimitri Mendeleev's version of the periodic table is one of the most important in history. That is because he created the first known periodic table out of 63 elements.
On a periodic table.
Mendeleev supposed that a new row is necessary in the periodic table after the discovery of lanthanoides.
To understand the concept of Periodic Table
In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses and repeating periodic properties.
Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.
they changed the 3 new Elements.

Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.
Mendeleev's periodic table arranged elements by increasing atomic mass and grouped elements with similar properties together. Today's periodic table is similar, but it is arranged by increasing atomic number, which reflects the number of protons in an atom's nucleus. Both tables also show periodic trends in properties as you move across and down the table.
Scientists tried to improve Mendeleev's periodic table to account for the discovery of new elements, better organize elements based on their properties, and to address inconsistencies in the original table. This led to the development of the modern periodic table with elements arranged in increasing atomic number and grouped based on similarities in chemical properties.
Chemists in the early 1900s made changes to Mendeleev's periodic table by rearranging elements based on their atomic number instead of atomic mass, leading to the development of the modern periodic table. This change accurately emphasized the relationship between an element's properties and its atomic number, rather than its atomic mass, and helped to better organize the elements.
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.
Dobereiner, Newland , Mendeleev are responsible for development. Modern periodic table was created by Henry Moseley.
