No, John Dalton did not create the periodic table. While Dalton made significant contributions to the field of chemistry, he is best known for his work on atomic theory, which laid the groundwork for understanding the composition of matter.
Dalton proposed that each element is made up of atoms of a specific weight and that these atoms combine in fixed ratios to form compounds. His research was instrumental in advancing the study of chemistry during the early 19th century.
The first periodic table, however, was created by Dmitri Mendeleev in 1869, several decades after Dalton’s work. Mendeleev’s periodic table organized elements by their atomic weights and properties, leading to the modern understanding of the periodic classification of elements.
In summary, while Dalton’s atomic theory paved the way for future developments in chemistry, it was Mendeleev who created the periodic table we recognize today.
