He determined the number of positive charges in the nucleus of an atom. He was the first one to bring the concept of atomic number.
Neil bohr has done research in quantum mechanics.
I think it was that he theorized that when a new substance is made, the elemnts didn't change the atoms just rearranged. I'm not certain though. Galileo is more known for his research on planets.
Nothing. He contributed to the evolving body of speculation about the atom, by translating Epicurus who had developed his ideas from Leucippus and Democritus; but nothin to its history
He proposed the wave-particle duality for the electrons.
Dalton's atomic theory was a major contribution to discover the atomic structure in despite of been completely counterproved.
Moseley was the first to clear and scientifically justify in 1913 the atomic number studying X-ray spectra of chemical elements. But Moseley hadn't a personal atomic theory, he was not the discoverer of the atomic theory.

Antoine Lavoisier was a French nobleman and chemist. His contribution to the development of the modern atomic theory was his idea of the possibility of an Atomic Mass.

The contribution of anyone prior to about 1600 to the development of atomic theory might as well be "nothing whatsoever." Democritus and/or Leucippus contributed the name "atomos", but not much else; they were wrong about nearly every detail. John Dalton is just about the earliest scientist to have had any significant contribution to atomic theory, and most of what we now consider atomic theory was developed since about 1900.

They didn't help with atomic theory, they created it.
That the cake is a lie.
