What is the atomic model timeline?
The following timeline of the atomic model is highly condensed and omits many important contributions.
442 BC — Democritus/Leucippus — matter consists of indivisible particles.

1869 — Dmitri Mendeleev — Periodic Table and periodic law
1897 — J. J. Thomson — discovers electron
1898 — J. J. Thomson— plum pudding model of atom
1898 — Ernest Rutherford — discovers α and β rays
1900 — Frederick Soddy — discovers radioactive decay
1900 — Max Planck — quantum theory of energy
1905 — Albert Einstein — Quantization of light; ##E = mc^2##
1909 — Ernest Rutherford — nuclear model of atom
1913 — Niels Bohr — orbital model of atom
1914 — H. G. J. Moseley — measures atomic numbers of nuclei
