Question

What are two of the early atomic models that contributed to the formulation of the modern atomic theory?

Answer 1

Niels Bohr's Planetary model and the Plum Pudding model (think this was Thompson's creation but it validated by Rutherford).

Both Bohr's planetary model and Thompson's Plum pudding model have been replaced by the modern quantum mechanical model.
