What is the correct chronological order of scientists contributing to the modern periodic table?

Answer : Lavoisier was the first to contribute towards modern periodic table. He was considered as Father of modern chemistry who was a French nobleman prominent in the histories of chemistry and biology. His works helped to reform chemical nomenclature.

Dobereiner was assumed to be the second who contributed to modern periodic table by discovering that the relative atomic mass of the middle element in each triad was found to be close to the average of the relative atomic masses of the other two elements.

Newlands is on third number of the chronological order for contributing towards modern periodic table as he was the one to arrange all the elements known at that time into a table in order of relative atomic mass. When he did that, he found that each element was similar to the element eight places further on.

Mendeleev was the fourth in the list to contribute for the modern periodic table as he was a Russian chemist who published a periodic table. He also arranged the elements known at that time in order of relative atomic masses.

Moseley is considered to be the last to contribute towards modern periodic table as he arranged the elements in the periodic table by their number of protons rather than their atomic weights.
