Which scientist is credited with developing the first scientific atomic theory

John Dalton

Explanation:

John Dalton, a chemist by training, was born in the county of Cumbria, England, in 1766 and died in the city of Manchester in 1844. His early life was devoted to scientific research and teaching, so much that he taught or contributed to the development of various knowledge areas.

His greatest legacy as a scientist, however, was the development of the first atomic theory. It was through various experiments related to the gas mixture and the knowledge of the works proposed by Lavoisier that Dalton's atomic theory emerged in 1808.

Dalton's atomic theory was fundamental to the development of atomic knowledge, as it served as a basis for other scientists to know the atom and its characteristics.
