1major contributions to the atomic theory
2a descrition of their atom model
3was his theory tested and published?
4was valid experimentation done to provide usuable data which supported the theory>?
5was the theory accepted by peers?
6is the theory still applicable today?
answer these questions for the following men:
moseley, leucippus, chadwich, democritus, geiger, aristotle, planck, thomson, millikan, bohr, einstein, dalton, rutherford.
any help is greatly appreciated!! 10 points to who ever can give me the most info!

Leucippus, a Greek philosopher, was the first person recorded to believe that all matter consisted of atoms. He believed that everything was made up of tiny and indivisible particles called atoms. The word atom comes from the Greek word ‘atomos’, which means not divisible.
According to Democritus, another Greek philosopher who agreed with Leucippus said, these atoms were not all alike. He said that they differ in size and shape, and that substances were different from each other because they were made up of different types of atoms
a. Dalton's atomic theory stated that atoms could not be created or destroyed. He said that the atoms were rearranged in chemical reactions. This rearrangement rather than creation or destruction explains why mass remains constant in chemical reactions.
b. Dalton's atomic theory said that combinations of atoms made compounds. The same combination of atoms would lead to the same compound every time, giving the same percent composition of the elements involved and the same properties for the compound.
c. Dalton's atomic theory said that combinations of atoms made compounds. The same atoms could be combined in more than one different way, giving different compounds. For example, two different compounds form between hydrogen and oxygen. Hydrogen peroxide (H2O2 has twice as much oxygen for the same mass of hydrogen as water (H2O). daltons theoryy is still aplicable today.

I know that Rutherford was the first to correctly find the description of an atom.
