The atomic theory of John Dalton is from 1801-1802.
John Dalton's atomic theory did not support Aristotle's ideas; in fact, it contradicted them. Aristotle believed that matter was continuous and composed of four elements (earth, water, air, fire), while Dalton proposed that matter is made up of indivisible atoms, which are the fundamental building blocks of all substances. Dalton's theory laid the groundwork for modern chemistry, moving away from Aristotle's qualitative approach to a quantitative understanding of matter.

The term used by Democritus to identify the particles of an element is atomic theory. It was thought up by John Dalton between the years 1766 and 1844.
It depends. If you mean just any old atomic theory, credit usually goes to either Democritus or his mentor Leucippus. However, if you mean an atomic theory that wasn't totally blowing smoke out their nether regions, was backed up by actual experimental data, and at least resembled the truth in certain ways if you squinted hard enough, I'd say John Dalton is probably your guy.

scientific method used in the development of atomic theory
This quote is attributed to British physicist and chemist John Dalton, who proposed the atomic theory of matter in the early 19th century. Dalton's theory stated that all atoms of a given element are identical and have specific characteristics that differentiate them from atoms of other elements.
