john Dalton died in 1854. The first periodic table was published in 1869. But john Dalton did put forward the first clear idea of atoms and molecules.
De Chancourtois is known for his contribution to the development of the early periodic table of elements. He arranged the elements in a spiral or helical format based on atomic weights, which foreshadowed the modern periodic table structure. This arrangement helped in understanding the periodic trends and relationships between elements, paving the way for the organization of elements we use today.
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
Dmitri Mendeleev created the periodic table of elements, arranging elements by atomic mass and properties. His contribution revolutionized the field of chemistry by predicting the existence and properties of undiscovered elements. Mendeleev's periodic table provided a framework for understanding the relationship between elements and laid the foundation for modern chemistry.
He found the number of protons an element has. present periodic table is according to it.
There are 53 Elements in the Periodic Table.
1) Dalton never proposed any table 2) All elements in Mendeleev's table and in the modern periodic table are elements.
In chemistry all most all elements properties are known based on 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 arranged elements in order of increasing atomic masses. He considered chemical properties of the elements.
Henry Moseley showed elements in the periodic table should be in order by their atomic number instead of atomic mass.
