What was the date that Niels Bohr discovered atomic theory?
Niels Bohr's atomic theory, known as the Bohr model, was proposed in 1913. This theory revolutionized our understanding of atomic structure by introducing the concept of quantized energy levels within the atom.
When John Dalton date of discovery?
John Dalton discovered the atom in 1803. He didn't really discover the atom. He developed a theory of matter that involved atoms. Atoms were proved to exist later.

Who was the first person to say that matter was made up of tiny solid atoms?
Democritus was the one who came up with the concept and the name (atomos in Greek means "no-cut"). Democritus was mostly lucky, not prescient; the scientific method in ancient Greece largely consisted of coming up with as many wacky ideas as they possibly could, under the theory that eventually someone's wacky idea was bound to be right.
What was the first idea about the atom?
Theories about the composition of matter date back to the ancient Greeks. In about 450 BC, Democritus theorized that matter consisted of átomos (means uncuttable), or atoms. Modern realization of atomic theory began in 1661 when Robert Boyle therorized that there was an end to the ability of chemistry to break down substances (he called atoms "corpuscules"). Up to that point, classical chemists thought substances were formed from combinations of the 4 classical elements: air, earth, fire, and water. Then, in 1789 the term "element" was defined by the Frenchman Antoine Lavoisier to mean basic substances that could not be further broken down by the methods of chemistry. From there, John Dalton proposed that gases were made of individual particles that could combine to form unique compounds. By 1905, the existence of atoms was pretty much universally accepted when Einstein published his papers on Brownian motion (random motion due to the energy in atoms). Sorry, but atoms were never really just "found", they were gradually noticed over centuries, and now it's accepted as the best explanation for what we can see.
